Abstract: The machine initiated maintenance system (10) makes use of a memory (90) on each field replaceable unit (70) within the customer system (40) to provide history data on a filed replaceable unit basis. In particular, data is written into the field replaceable unit (70) to identify the content and repair status of the field replaceable unit (70) as well as prior maintenance activity in which the field replaceable unit (70) was identified as a suspected failed unit. The memory (90) can contain varying quantities of data indicative of the performance and life history of the field replaceable unit (70) as well as the various environments in which it was operational, including identified failures.

Abstract: This apparatus (100) makes use of a disk drive array to store the data records for the associated host processor (11, 12). This disk drive array emulates the operation of a large form factor disk drive by using a plurality of interconnected small form factor disk drives (12*-*). These small form factor disk drives (12*-*) are configured into redundancy groups (421-428), each of which contains n+m disk drives for storing data records and redundancy information thereon. The use of this configuration is significantly more reliable than a large form factor disk drive. However, in order to maintain compatibility with host processors (11, 12) that request the duplex copy group feature, the pantom duplex copy group apparatus of the present invention mimics the creation of a duplex copy group in this dynamically mapped data storage subsystem (100) using a disk array and a phantom set of pointers (414) that mimic the data storage devices (421) on which the data records are stored.

Abstract: The data record copy apparatus for a virtual memory system (120) instantaneously makes a copy of a selected data record (Record 4) by simply generating a new set of pointers (201-2) to reference the same physical memory location (214) as the original reference pointer (200-n). In this fashion, by simply generating a second set of pointers (201-2) referencing the same physical memory space (214), this apparatus effectively makes a copy of the data record (Record 4). A second physical copy of the data record (Record 4) can later be created as a background process or can be delayed until a modification is made to the data record (Record 4) by one of the two programs that access the data record (Record 4).

Abstract: The multiple step data read apparatus provides a buffer memory (108-0) for each read/write head (110-0) in the rotating media (111-0) data storage system that can store up to the entire track (400) of data that includes the requested data (Sectors 2-6). The data is fragmented such that the data transferred into the read/write head buffer (207) first is transmitted to the control unit (104) first whether or not that data is at the beginning of the data requested by the control unit (104). The data is further fragmented such that critical portions of the data are available to the control unit (104) to satisfy the host request as soon as the data is read from the device. This fragmenting results in the data becoming available to the control unit (104) in the mininum time possible and the performance of the subsystem (120) being the maximum possible. In addition each data fragment transfer to the control unit (104) is initiated a predetermined time before the end of the fragment of data such that the read/write head (110-0) reaches the end of the fragment the same time that the last sector of the fragment is transmitted to the control unit (104).

Abstract: A process for fabricating a thin film magnetic head (13) to achieve improved dimensions and tolerances of the pole tip portion of the head. A lower thin film magnetic layer (1) comprising the lower pole tip is first formed followed by a thin layer (2) defining the gap of the head. A thin film magnetic layer (3A) is then deposited only in the vicinity of the pole tip to define the upper pole of the head. Following this, successive layers of insulation and coils are deposited. Finally, a top thin film magnetic layer (8) is deposited. This top layer contacts the already formed layer comprising the top pole piece.

Abstract: The apparatus for writing data (109) on a magneto-optic recording medium (100) provides simultaneous erasure of old data and writing of new data with one laser beam (110). This is accomplished by operating the laser (104) in the continuous power mode and reversing the magnetic field in synchronization with the data (109). This apparatus includes an annular or doughnut-shaped magnetic transducer (103) which provides a switchable, vertically oriented magnetic field that is applied to the magneto-optic recording medium (100) through the hole in the annular magnetic transducer (103) and is focused on the surface of the recording medium (100) to provide the heat necessary to render the recording medium (100) susceptible to magnetization.

Abstract: The automatic magnetic tape cartridge stack loader apparatus includes a stack load slot (100) for receiving a stack of magnetic tape cartridges (701). This slot is supported on the bottom by an indexing mechanism that translates the stack of magnetic tape cartridges in a downward direction so that the bottom most magnetic tape cartridge in the stack is in position in front of the tape drive access port, and supported by a load mechanism for insertion into the tape drive. A pair of stack grab plates (101, 102), located on either side of the stack load slot concurrently operate to clamp the stack of magnetic tape cartridges, less the bottom most one, as the stack is translating in the downward direction. Once the bottom most magnetic tape cartridge is positioned on the load mechanism, the drop mechanism is operated to be repositioned under the stack of magnetic tape cartridges held by the stack grab plates. A tractor mechanism (126) is then activated to load the magnetic tape cartridge from the load mechanism into the drive. When the magnetic tape cartridge is ejected from the tape drive, the tractor mechanism loads it onto the load mechanism where it is placed on to an elevator mechanism (112) that supports a stack of ejected magnetic tape cartridges.

Abstract: An early end of tape sensing subsystem for a data processing system, including a host computer, a cache buffer (35), and a magnetic tape drive subsystem utilizes outputs dependent upon the movement of a capstan wheel (11), swing arm (13), and file reel (15) of the magnetic tape drive subsystem, determining the net movement therein in order to mesure the circumference of the file reel (15) plus tape thereon. Whenever a series of valid readings from a conventional sensor (41) are obtained indicating that the circumference of the file reel (15) plus tape is approaching that of the circumference of the file reel (15) itself (i.e., no tape on the file reel (15)), a signal is sent to a microprocessor (33) controlling the cache buffer (35), said signal indicating that the end of the tape is approaching.

Abstract: A current transformer (17), magnetically coupled to the ferro-resonant circuit (18) of the ferro-resonant transformer (19) is used to sense the current flowing in the ferro-resonant circuit. A fault detection circuit (20), powered by its own power supply (32) connected to the primary source of power (8), monitors the sensed current and signals any significant change therein. A fault condition in any of the secondary circuits of the transformer causes the ferro-resonant current to change, and upon sensing this change, the fault detection circuit disconnects the primary of the transformer from the source of power.

Abstract: An improved circuit for encoding data to be stored according to a 2,7 run-length limited code, which features substantial simplification compared with prior art circuitry. The simplified circuit uses half as many memory elements as the prior art circuit and employs Boolean identities to simplify the logic elements encoding the data. In a preferred embodiment, the circuit is implemented using emitter-coupled logic. If necessary, the capacitance required by resistor-capacitor networks used to eliminate race conditions may be formed between a planar conductor on one side of a circuit board on which the circuit is laid out and a circuit element on the other.
