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: 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, a disk (44) housed in a cartridge (32), my 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 (18), 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 acces to the available storage space. The disk (44) is divided into data bands, each data band having a prescribed number of concentric data tracks therein. Each data track 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. 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 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 shared encoder/decoder circuit 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. The same circuitry (161) 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 (172). The output of the adding circuit is fed back to an input to the RAM (165). Two multiplier circuits (168, 170) are coupled to the output of the RAM. 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 module 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: A linear detector (31) for use in a coarse positioning servo system of an optical disk storage system. The linear detector produces an error signal (67) having an amplitude linearly proportional to the distance that a center of mass of incident radiant energy (63) falls on a collection surface (62) of the detector as measured relative to a fixed reference point on said collection surface. Two reference signals (65, 66) are derived from circuitry associated with the collection surface. A first reference signal (65) has an amplitude proportional to the intensity of the focussed light energy and the location that said light energy falls on the collection surface relative to a first reference point. A second reference signal (66) has an amplitude proportional to the intensity of the focussed light energy and a location that said energy falls on the collection surface relative to a second reference point. The sum and difference of the amplitudes of the first and second reference signals are derived to produce sum and difference signals (Y, X), respectively. The difference signal is divided by the sum signal (X/Y) to produce the desired error signal, which error signal has an amplitude that is substantially independent of the intensity of the focussed light energy. Signal processing circuitry (84, 86, 88; and 85, 87, 89) may be used to demodulate the reference signals so that the desired error signal is derived only from that portion of the incident radiant energy reflected from a coarse servo track of the optical disk, and not from radiant energy reflected from other areas of the disk.

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.

Four individual photo-detectors (37, 38, 39, 40) and two photo-detector quad arrays (41, 42), each consisting of four photo-detectors arranged in a rectangular shape, are precisely located on a single semiconductor chip.

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.
