Abstract

Alignment of a magnetic head support relative to magnetic media is tested and calibrated by substituting a physically identical alignment head. A head support normally retains a magnetic read/write head, having a constant radius contour, in contact with the surface of a magnetic media during reading and writing operations. For alignment, the magnetic head is removed and replaced by the alignment head having a probe matrix, which is connected to a visual display by a cable. The usual magnetic media is replaced by an otherwise identical media carrying a relatively conductive (silver, copper, aluminum, etc.) layer.

Alignment Head

Alignment of a magnetic head support relative to magnetic media is tested and calibrated by substituting a physically identical alignment head. A head support normally retains a magnetic read/write head, having a constant radius contour, in contact with the surface of a magnetic media during reading and writing operations. For alignment, the magnetic head is removed and replaced by the alignment head having a probe matrix, which is connected to a visual display by a cable. The usual magnetic media is replaced by an otherwise identical media carrying a relatively conductive (silver, copper, aluminum, etc.) layer.

Lamps in the visual display identify circuits completed through alignment head probes. The pattern of lights identifies the alignment precision. Ideally, the center light should be lit during relative head-media motion. Any number of probes may be used; nine are shown as an illustration.
