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.
Claims17
A magnetic disk cartridge for use with a disk drive of the type having a fixed Bernoulli plate against which a flexible magnetic disk is rotated in read/write relationship with a magnetic head, said cartridge comprising:
- a rigid box containing said flexible magnetic disk, said box having an opening in one side thereof through which said disk is rotated in said read/write relationship;
- and
- a slider which normally closes said opening, said slider being engaged by said plate when said cartridge is inserted into said drive to move said slider to an open position in which said disk is rotated in said read/write relationship.
A magnetic disk drive of the type which reads and writes magnetically recorded information from a magnetic disk contained in a cartridge comprising:
- a Bernoulli plate fixed in said drive with an edge thereof in proximity to an opening in said drive through which said cartridge is inserted so that said edge of said plate enters said cartridge through an edge thereof to position said flexible disk against said plate;
- a magnetic head;
- and
- means for rotating said disk against said plate in read/write relationship with said magnetic head.
The combination of a magnetic disk drive and a disk cartridge comprising:
- a rigid box forming said cartridge;
- a flexible magnetic disk enclosed in said box;
- a Bernoulli plate fixed in said drive with an edge thereof in proximity to an opening in said drive through which said cartridge is inserted so that said edge of said plate enters said cartridge through an edge of said cartridge, said flexible magnetic disk being positioned against said plate;
- a magnetic head;
- and
- means for rotating said disk against said plate in read/write relationship with said magnetic head.
