Magnetic disk cartridge.

摘要

A cartridge has a flexible pad (15) which is disposed between a Bernoulli plate (13) and a magnetic disk (12) when the cartridge is inserted into the disk drive. The flexible pad (15) prevents ringing as the disk (12) is rotated against the Bernoulli plate. The cartridge is closed by a slider (18) which is opened when the cartridge is inserted into the disk drive to expose the magnetic disk (12) for rotation. This slider (18) has a locking mechanism (19, 20) which can be opened only when the cartridge is properly inserted into the disk drive.
