Abstract: An optical disk drive system with which data may be permanently and correctly stored on removable media. The system includes a drive (20) into which the media (44), a disk housed in a cartridge (32), may be removably inserted. The drive interfaces with a host CPU (22) through a storage control unit (24), which storage control unit may also have other peripheral devices, such as magnetic disk drives (28), coupled therethrough to the host CPU. A special data format is used for data stored on the disk in order to provide efficient use of and access to the available storage space. The disk is divided into data bands, each data band having a prescribed number of concentric data tracks therein. Each data track (74) is divided into equal length sectors. The data is organized into data blocks, each block being made up of a selected sequence of prescribed data sections (139', 141'). Many of the data sections commence with synchronization bits followed by the data to be stored. The data of each data section is adapted to fit within each data sector on the disk. When data is written in any given sector, it is immediately checked for correctness by reading the data that has been written and comparing it with the data that was to have been written. Defectively written data is flagged so that it can be skipped over and ignored during subsequent reads. Data in a given sector is rewritten until it is written correctly.

Abstract: A self-shared encoder/decoder circuit (161) for use with a Reed-Solomon coding scheme of an optical disk storage system. The optical disk system (20) includes a drive adapted to permanently store data on a removable platter (44). Prior to recording a data byte on the platter, the data is encoded with a Reed-Solomon code. When the data is read from the disk, it is decoded and error correction syndromes are generated with ECC generation circuits (164). A plurality of syndrome buffer registers are provided in order to allow several of the error correction functions to be carried out in parallel. Syndromes that are detected to comprise all zeros are used to simplify the error correction processes beyond the normal processes used. The same circuitry is shared for performing the encoding and decoding functions. This circuitry includes independent sets of a RAM (165), coupled to one input of an exclusive OR (modulo two sum) adding circuit (177). The output of the adding circuit is fed back to an input of the RAM (165). Two multilier circuits are coupled to the output of the RAM (165). A product of one is tied to one input of the modulo two addition circuit (172). The product of the other is combined in another modulo two addition circuit (173) with similar products from other sets, and the resulting combination signal is selectively connected to the other input of the modulo two addition circuit (172), along with data to be recorded on the platter, or data read from the platter.

Abstract: The centering and clamping device consists of six major components: a disk elevating and lowering means (13), a disk support means (16), a disk centering means (29), a disk clamping means (19), and a disk rotating means (9). In operation the disk is raised out of cartridge by the disk elevating means, and raised upward to engage the taper (29) on the spindle of the spin motor (9), moving upward until the cooperation between the taper on the next spindle and the tapering on the disk centering collar cause the disk to move laterally forward until precisely centered on the spindle. Thereafter, the continued upward movement on the disk on the elevator lifting means causes a magnet (20) located on the disk support means to come in magnetic contact with a steel plate (32) on the spindle platform, thereby securely clamping the disk to the spindle for rotation. Thereafter, the elevator means is moved downward and disconnected from the disk support means, allowing free rotation of the spindle disk and disk support means relative to a stationary elevating means. For removal, the above procedure is reversed.

Abstract: A carriage assembly (1) for use in optical recording apparatus wherein the carriage body (8) to which the sensing means are attached is mounted to the assembly guide (rails 6, 7) through the combined center of mass (29) of the carriage body and sensing means so that upon activation, the apparatus is not subjected to bending or torsional stresses which cause the tangential and radial tracking errors. By placing the center of mass in the plane of the bearing support, the carriage body can be constructed of lighter weight materials thus allowing for more rapid and precise assembly movement.

Abstract: An optical disk servo system includes a coarse access and tracking system (34) for optical head control and a fine access and tracking system (25) for read/write beam control. Enlarged servo tracks are pre-recorded on the optical disk between bands of data track locations. The coarse system illuminates a relatively large area of the disk surface encompassing at least one of the servo tracks and detects light from the enlarged illuminated area. Suitable means including a photo-detector array (31) identifies and controls the optical head position by means of the light returned from the illuminated servo track. Such photo-detection means are insensitive to light reflected from the data tracks. The fine access and tracking system uses a conventional, three spot tracking and read sytem, two spots for data track following and one spot for data track reading. The fine access and tracking system controls a galvanometer mirror (26) or other suitable means steering the read spot beams. Data writing is accomplished by fine tracking a previously recorded data track and maintaining the write beam a constant distance therefrom.

Abstract: A magnetic or optical disk load/unload device and method for automatically centering and clamping a disk (14) to the spindle (16) of an information storage device. The apparatus is comprised of a toggle arm (2); a toggle arm rotating means (3); a disk support base (4); a support hub (10) having a centering stem (13) and a concentric annular steel ring (12) disposed on its mating surface; a means for clamping the hub to the support base; a spindle (16) having a centering hole (17) on its mating surface and a concentric magnetic material ring (18) on its mating surface; and a spindle rotating means. In operation, the toggle arm is rotated from a first bent position causing the support base hub and disk located thereon to advance toward the spindle, the hub slidably retained on the base by a clamping member activated by a cam assembly. Upon full extension of the toggle arm, the hub and disk are centered on the spindle, clamped to same by the magnetic and steel rings. The toggle arm continues on to a second bent position, causing the support base to retreat from the support hub, the clamping member having been released. At this point the spindle, disk and hub are free to rotate. For unload, the above described procedure is reversed.

Abstract: A disk cartridge (1) for protecting a disk upon which digital information is stored. The cartridge includes a rectangular shaped cartridge housing (2) and a cartridge insert (3). The cartridge insert is removably disposed within the housing through a side opening (4) thereof. The side opening has an exterior taper (12) which closely engages a cooperating interior taper (13) of the cartridge insert so that a tight seal is formed when the cartridge insert is fully inserted into the cartridge housing. The cartridge insert is locked into the housing by a pair of latches (6) that form an integral part of the cartridge insert. These latches cooperate with catches (7) that form part of the housing to securely lock the insert inside the housing. Only through the use of special engaging pins may the latches be released to allow the cartridge insert to be slidably removed from the housing.

Abstract: A low cost flexural mechanism upon which tracking mirrors and the like used in optical systems may be mounted. The flexural mechanism is made from a single sheet of metal by placing a desired shape or pattern in the metal. The resulting shape is then formed in a base (35, 36), mounting surface (37), and flex arms (31-34). The mechanism is stiff in directions other than rotation, has low noise, has low thermal sensitivity, and can be made in any practical size. The flexural mechanism can be designed to place the pivot axis at the center of gravity of the mass being rotated, even when the center of the gravity is outside the flexural mechanism.

Abstract: Sector marks are selectively placed in each coarse servo track (M-15) of rotating disk (10). These concentric coarse seek tracks (11-15) pre-written on the disk (10), are used by a servo system for the positioning of the read/write mechanism. Coarse track read means simultaneously sense at least two adjacent coarse seek tracks (54-55). Detection means (60) sense the relative position of these coarse seek tracks (54-55) within the sensing range of the coarse track read means, and this position information is used by the servo system to selectively control the radial position of the coarse track read means with respect to the rotating disk (10). The sector marks written in the coarse seek tracks (11-15) are likewise detected, and a signal is produced indicating when each sector begins and ends. An oscillator (69) is locked to this sector signal such that a fixed number of cycles of the oscillator signal corresponds to the passage of one sector of the disk under the coarse track read means. A counter (70) is then used to count the appropriate number of cycles. An index mark (30), representing a zero degree reference point, is also placed in the coarse seek track (54). When sensed, the index mark (30) resets the counter (70). The count contained in the counter thus always indicates the rotational position (sector location) of the disk (10).
