ABSTRACT:
A disk drive system with a disk loading/ejection control mechanism, includes a disk insertion detection switch for detecting an insertion of a disk and a first cam member for controlling loading and ejection operations of the disk. The first cam member is rotated by a driver to perform loading and ejection of the disk. A loading/ejection position detection switch detects both loading and ejection positions of the disk. A second cam controls the loading/ejection position detection switch, the second cam being co-operatively operated with the first cam. A controller is responsive to the operation of the disk insertion detection switch to drive the driver, and is responsive to both the leading and trailing edges of an output from the loading/ejection position detection switch, for detecting the disk loading and ejection positions to control the driver.
