Abstract
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 magnetic disk drive for writing and reading data to and from a magnetic disk contained in a cartridge which is inserted through an opening into said disk drive comprising:
- a yoke rotatable about a pivot in said disk drive;
- a motor having a spindle for engaging said magnetic disk to rotate it, said motor being mounted on said yoke so that rotation about said pivot moves said motor out of engagement with said disk and opposite rotation of said yoke moves said motor into engagement with said disk;
- and
- a shaft having a handle on one end and a cam on the other end, said shaft being rotatably mounted so that said cam bears against said yoke to rotate it when said handle is turned.
