Abstract: A magnetic disk drive has a drive motor mounted on a yoke which is rotatable about a pivot in the drive. A bezel member mounted on the end of the yoke normally closes the opening in the disk drive through which a cartridge is inserted. As this bezel member is moved out of the cartridge, the motor is moved out of the position in which it engages the disk and when the bezel member is closed, the motor moves into the engagement position. The motor is mounted on the yoke with a movable connection so that it is guided in a linear movement into engagement with the motor. In one embodiment the motor is guided by a shaft extending from the drive base plate through a guide opening in the motor.

Abstract: A cartridge for a flexible magnetic disk includes a rigid box with an opening on one side which is normally closed by a slider. When the cartridge is inserted into the drive, the slider moves to the open position in which the disk can be engaged to rotate it in read/write relationship with a magnetic head. As the cartridge is inserted, a fixed Bernoulli plate in the drive enters the cartridge through an edge thereof. The disk is rotated against the Bernoulli plate to provide stability.
