LASER ASSISTED TRACK WIDTH DEFINITION AND RADIAL CONTROL WITH MAGNETIC RECORDING

摘要

The present invention provides for the enhancement of the storage capacity of a data disk drive while reducing optical path optics, electronics and/or the mass and complexity of associated read/write heads. The system utilizes light transmitted by optical elements (102, 400) to servo track a data disk (107) and to heat the data disk during reading and writing of data, and magnetic elements for actual reading and writing.
