Patent ID: 7929255

Claim:
A magnetic head inspection system comprising one or a plurality of inspection modules each of which includes: a magnetic disk where servo data including track identifier information are recorded; a spindle motor to rotates the magnetic disk; a support member which has a mount structure to which a head assembly including a magnetic head is detachably secured and can pivot around a pivot axis defined outside the magnetic disk; a voice coil motor which drives the support member to pivot so that the magnetic head included in the head assembly mounted on the support member is moved over the magnetic disk substantially in a radial direction thereof; and a main circuit section which is electrically connected with the magnetic head included in the head assembly mounted on the support member and can execute read write control to read data from and write data to the magnetic disk by the magnetic head and positioning control to drive the voice coil motor based on the servo data included in the data retrieved from the magnetic disk; wherein each of the one or plurality of inspection modules is provided with an inspection circuit section which instructs the main circuit section to execute the positioning control to move the magnetic head included in the head assembly mounted on the support member to a specific track on the magnetic disk and the read write control to perform a certain read write operation by the magnetic head in order to inspect the performance of the magnetic head.
