Reduced profile magnetic head assembly and method of manufacturing reduced profile magnetic head support structure

摘要

A magnetic head assembly comprises a magnetic head, a magnetic head support structure having a first mount, a second mount and a housing space, and an optical unit fixed to the second mount, capable of projecting a plurality of light beams through a light passage on a recording medium and of receiving a plurality of reflected light beam. The optical unit comprises a light emitting device which emits a light beam, a holographic unit capable of producing a plurality of light beams from the light beam and of focusing the plurality of light beams on a position sensing track formed on the recording medium, and a photodetection device for receiving the plurality of reflected light beams. The holographic unit is partly received in the housing space.
