摘要： An optical information recording-and-reproducing unit includes a diffraction section provided with a reflected optical beam reflected on a storage medium. The diffraction section has at least first and second areas, and from each of the first and second areas, a +1-order diffraction light and a -1-order diffraction light are produced. The unit further includes first and second optical detection sections respectively provided with one of a pair of +1-order diffraction lights and a pair of -1-order diffraction lights produced from the first and second areas of the diffraction section. The unit still further includes a first circuit section for generating a tracking error signal based on output signals of the first and second optical detection sections. In the unit, the light provided to the first optical detection section forms a first spot in a far-field state before convergence, and the light provided to the second optical detection section forms a second spot in a far-field state after convergence.

摘要： A thermally assisted magnetic recording method is implemented for a storage disk with a magnetic recording layer which includes recording areas and non-recording areas. In this method, a heating laser is moved relative to the disk in facing relation to the magnetic recording layer for locally heating the recording areas. As the laser spot transitions from a recording area to the subsequent non-recording area, the heating is stopped. In cooperation with the heating laser, a magnetic field applier locally magnetizes the recording areas of the magnetic recording layer for recording signals. As the magnetic field applier transitions from a recording area to the subsequent non-recording area, the application of the magnetic field is stopped after the heating by the heating laser is stopped.
