Abstract
A recorder for a cartridge-enclosed disk includes a loading and unloading mechanism which utilizes a cam and cam-follower to enable a cartridge-receiver unit to automatically open the recorder's pivoted door when the receiver unit itself pivots from an operative to a loading/unloading position. The cam and cam-follower also enable the door to pivot the receiver unit to the operative position when the door is manually closed following insertion of the disk cartridge. A manually-releasable latch holds the receiver unit in its operative position against the action of a pivot-inducing bias spring. Until activated to allow the receiver unit to force open the door, the same latch also holds the door in its closed condition.
