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.
