Abstract: The present invention provides an inspection apparatus for inspecting an object such as an information storage medium or an information recording/reproducing head under set inspection conditions, which comprises: a sensor for identifying the type of object set for inspection by its size, and automatic inspection condition setting means for automatically setting the inspection conditions for the object to be inspected which are associated with the type identified.

Abstract: A stepping motor control apparatus comprises current computing means for computing a motor-coil exciting current corresponding to the holding position from a predetermined wave form pattern; micro step driving means for driving the stepping motor toward the final holding position through a micro step transfer distance shorter than a regular step transfer interval by exciting the motor-coil by application of the exciting current obtained from the computing means; and acceleration control means for controlling the stepping motor acceleration by switching on and/or off the exciting current of the motor-coil in accordance with an acceleration signal.
