ABSTRACT:
A method of this invention includes engaging a disk drive spindle motor with a disk cartridge. This method may include inserting a disk cartridge into a disk drive. After the disk cartridge has been inserted, the method may include rotating the spindle motor at a speed that is less than a critical speed and engaging the spindle motor with the disk cartridge at a speed that is less than the critical speed. After the spindle motor is engaged with the disk cartridge, the method of this invention may further include rotating the disk drive motor and thereby rotating the storage medium disposed within the disk drive at its operational speed. In order to accomplish this method, the system of this invention may include a microprocessor coupled to the disk drive spindle motor and a computer readable storage device. Preferably, this storage device contains programmed code and data for controlling the microprocessor to rotate the spindle motor at a speed that is less than a critical speed so that when the spindle engages the hub of the disk cartridge, the hub moves to a centered position with respect to the spindle.
