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.
