Abstract:
An anti-jam system (20) for a removable cartridge storage device (22) can accept a cartridge (24) containing data includes an anti-jam cam arrangement (34) which is mounted on a door (30) of the data storage device (22). As the door (30) is moved to a closed position, the anti-jam arrangement (34) engages a recess (61) in the cartridge (24) in order to urge the cartridge into the final registration position in the drive (22).
Abstract:
A removable cartridge disk drive (100) that receives cartridges at an angle relative to the base of the drive. The removable cartridge disk drive ejects cartridges (101) at an angle relative to the base of the drive such that the cartridge opens the disk drive door (286). The removable cartridge may contain multiple disks and is further configured to conform to a 3.5 inch form factor while the corresponding disk drive has a drive height of 1 inch or less. The removable cartridge disk drive also has a bent wire (246) mounted to a suspension on the actuator (110) that engages a head load/unload ramp while a head is over the disk, thereby permitting the disk drive to utilize a stationary head load/unload ramp. The disk drive further has a Burst In Range mode that ignores servo errors unless the servo error occurred during a target data sector and unless the servo error is a certain type of servo error. A history of recent error conditions is maintained. The Special Data Sector mode identifies the exact data sector during which a servo error was detected. The removable cartridge used by the disk drive has an anti-rattle feature.
Abstract:
The system invokes a learning subroutine (600) under which a set of error location vectors are established, one for each possible location of the defective servo sample. With each error location vector, if the performance improves when it is applied then the estimation is taken to be correct, and the location of the defective sample is saved. If the performance is worse upon application of the error location vector, then the estimation is taken to be incorrect, and a different error location vector is used. During further read and write operations with the disk, the system may ignore the position error signal at the bad servo sample locations, or may adjust for bad servo samples by using a compensating position error signal vector.
Abstract:
A disk drive (30) for receiving a removable cartridge (200) having a recess (266, 270) formed in an exterior surface thereof, and an engaging surface of the disk assembly mounting mechanism (56) is located in that recession. The drive possesses a handle (58) having a lever (70) which extends into the recess to contact the engaging surface of the disk assembly mounting mechanism, whereby further movement of the handle causes the mounting mechanism to move in such a manner that a disk assembly within the removable cartridge is positioned over a spindle motor (54) of the drive for mounting thereto. Other features such as position sensors and enhanced cartridge positioning mechanisms are also provided.
Abstract:
A disk drive (30) conforms to the 1.8 inch form factor through use of, for example, a removable cartridge (200) which has a disk (220) mounted on the hub (226) which hub (226) is manipulatable by a multifunction handle (58) of the disk drive (30), allowing the hub (226) to be seated on the spindle motor nose (56) of the disk drive (30). The multifunction handle (58) of the drive (30) provides for a compact, high capacity design by performing cartridge hub seating operations, cartridge ejection operations, head arm assembly unlocking operations, and handle locking and unlocking operations to ensure proper operation of the disk drive (30). The disk drive (30) includes an inventive ramp (66) design which allows the head arm assembly (64) to be initially received within the cartridge (200) as the cartridge (200) is inserted into its final registration position in the disk drive receiving mechanism (53) and to be more tangent with respect to the disk (220).
Abstract:
A cartridge (20) for a disk drive (130) includes a door (44) which can be urged from a closed position to an opened position which is substantially within the cartridge (20) and located in a plane substantially parallel to the disk (42) contained in the cartridge (20). The cartridge (20) includes a mounting mechanism (48) for accomplishing the motion of the door (44) from the closed to the opened position and a locking mechanism (50) for locking the door (44) in the closed position. Further, the cartridge (20) includes a groove (52) which extends rearwardly and across the cartridge in order to lockingly engage the cartridge in the drive (130).
