Abstract
Embodiments of the present invention provide a magnetic head inspection system having a simple configuration capable of inspecting magnetic heads. According to one embodiment, the magnetic head inspection system comprises an inspection module which is provided with a magnetic disk where servo data including track identifier information are recorded, a spindle motor, a carriage having a mount structure to which a head assembly containing a magnetic head is secured, a voice coil motor and a main circuit section. An inspection circuit section instructs the main circuit section to execute control so as to move the magnetic head to a specific track and perform a certain read write operation by the magnetic head in order to inspect the magnetic head.
