A movable platform is mounted on opposing guide rails within a disk drive. A head actuator and spindle motor are mounted on the movable platform. The platform moves on the guide rails from a forward position to a rearward position upon insertion of a disk cartridge into the disk drive. As the platform moves toward the rearward position, the elevation of the platform changes in order to bring the spindle motor into engagement with the hub of the disk cartridge. A latch member is pivotally mounted on one of the guide rails for latching the platform in its forward position when the disk drive is not in use.

Movable internal platform for a disk drive

A magnetic head assembly having a flat surface for disposition adjacent to a recording medium and a protrustion in the range of about 1 to about 20 micro-inches on the flat surface effects coupling of the head assembly to the recording medium and creates a constant contact zone, surrounding the read/write gap of the head assembly, between the head assembly and the record medium. The preferred range for the protrusion is about 6 to about 8 micro-inches and the area of the flat surface is preferably in the range of about 3 to about 4 square millimeters.

Bernoulli effect transducer coupler

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.

Record disk cartridge with flexible pad

A cleaning cartridge for a magnetic disk drive has a flexible cleaning pad on a wiper assembly which is rotatable in the base of the cartridge. A knob on the outside edge of the cartridge is moved back and forth to rotate the wiper assembly by a cable attached to the hub. As the assembly rotates, a cam surface forces the flexible pad into engagement with the head to clean it.

Head cleaning cartridge for magnetic disk drive

A magnetic disk drive for writing and reading data to and from a magnetic disk contained in a cartridge which is inserted through an opening in the disk drive includes a drive motor rotated on a yoke by a manually operated shaft having a handle on one end and a cam on the other end. A flat diaphragm switch is operated by a rotation stop on the shaft to indicate when the motor is in the loaded position of engagement with the disk.

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