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. Further interlocking device 100 is provided for ensuring that the cartridge 52 cannot be removed from the receiver 60 when the spindle motor 102 is engaged with the disk 256 and for ensuring that the drive 50 cannot be enabled if the cartridge 52 is not received in the receiver 60.
