Abstract

A cartridge has a flexible pad which is disposed between a Bernoulli plate and a record disk when the cartridge is inserted into the disk drive. The flexible pad prevents ringing as the record disk is rotated against the Bernoulli plate. The cartridge has a slider which is opened when the cartridge is inserted into the drive to expose the record disk for rotation. This slider has a locking mechanism which can be opened only when the cartridge is properly inserted into the drive.
