ABSTRACT:
A magneto-optic disk drive includes cartridge-receiving guide tracks and a push-latch mechanism mounted in an upper portion of a half-hight enclosure, and a baseplate assembly pivotally mounted in a lower portion of the enclosure. The baseplate assembly includes a baseplate, a drive motor and spindle mounted to the baseplate, and a rotary arm mounted to the baseplate by a pivot mechanism. Optical head components including a focusing and bias field switching assembly are mounted to the rotary arm. A tracking motor includes coils mounted to an end of the rotary arm directly adjacent to the focusing and bias field switching assembly, and permanent magnets mounted to the baseplate. An optical disk cartridge is pushed into the drive and latched into its inserted position when the baseplate assembly is in a load/unload position. A baseplate drive mechanism raises the baseplate assembly to its operative position causing the drive motor and spindle to engage and rotate the optical disk. The tracking motor drives the rotary arm about a tracking axis allowing data to be written, read and erased on the disk. Cartridge removal is initiated by pressing a stop switch. After the disk spins down to a stop the baseplate assembly is driven to its load/unload position. When pushed, the cartridge is unlatched and ejected from the drive.
