Electromechanical devices frequently have a requirement to orient a motor driven part to a nominal starting position. An example of such a device is the read/write head of a flexible disk drive which is driven to an initial position during power up or whenever the controller has lost track of the head position. The most economical implementation is to continuously access the head toward a home track until a mechanical stop is reached. This approach does have wear and noise disadvantages when compared to more costly alternatives.
