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.

Abstract: An alternating "A/B" servo burst pattern for measuring and compensating for offset of the track centerline due to differential magnetic influence to the servo pattern, and a switching network to alternate the output of the servo system demodulators between the inverting and non-inverting terminals of a differential amplifier so that electrical distortion is minimized.

Abstract: A cartridge 52 adapted for being inserted into a disk drive 50 includes a housing 70 which contains a disk 256 mounted for rotation and an interlocking device 90 defined in the housing 70 and adapted for automatically lockingly positioning the cartridge 52 in the disk drive 50 as the cartridge 52 comes to a final position relative to the disk drive 50. The interlocking device 90 includes an element 90 which is defined in the cartridge housing 70 in the direction which is substantially across the direction of insertion of the cartridge 82 into the drive 50. The interlocking device 90 includes a recess 90 for lockingly positioning the cartridge 52 which recess 90 includes an opening 360 disposed through the front edge 98 of the cartridge 52 and which is directed therefrom in a direction which is substantially across the direction of insertion of the cartridge 52 into the drive 50.

Abstract: A disk drive 50 for receiving a removable cartridge 52 containing a disk 256 for storing data. The disk drive 50 includes a spindle motor 102 for engaging and causing the disk 256 of the cartridge 52 to spin at an appropriate speed and a mechanism 168 for mounting the spindle motor 102 to the disk drive 50 so that the spindle 102 motor is movable from a first position out of engagement with the disk 256 to a second position operably engaged with the disk 256. The spindle motor 102 can thus move in a plane which is not coplaner with the cartridge receiving plane. The disk drive further includes an ejecting mechanism 106 for engaging and lockingly holding the cartridge 52 in place in the cartridge receiver 60 and for ejecting the cartridge from the cartridge receiver 60.

Abstract: A disc drive (420) includes a spindle motor (432) having a stator assembly (436) which is provided in a radial gap configuration. A removable cartridge (422) includes a rotor assembly (472) mounted on a bearing arrangement (468) which additionally mounts the disc (430) contained in the cartridge (422). When the cartridge (422) is placed in the drive (420), the rotor assembly (472) of the cartridge (422) comes into alignment with the stator assembly (436) of the drive (420) so that the spindle motor (432) can cause the disc (430) contained in the cartridge (422) to rotate at the proper speed.

Abstract: A disc drive 20 including a spindle motor assembly 42 having a magnetic clutch plate 46 and an actuator 47 receives a hermetically sealed cartridge 22 containing a plurality of discs 72, 74 with associated heads 80, 81 mounted in the cartridge 22. Associated with an arm assembly 84 which supports heads 80, 81 is a component 50 for use with the actuator 47. With the cartridge 22 inserted in the drive 20, the actuator 47 operates to cause the heads 80, 81 to traverse relative to the discs 72, 74 as the spindle motor assembly 42 uses a magnetic field to engage a magnetic plate 77 associated with cartridge 22 in order to spin the discs 72, 74. Data transfer connectors 52, 54 are associated with both the drive 20 and the cartridge 22 in order to allow for the transfer of data between the cartridge 22 and the drive 20.
