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.

摘要： A master medium for magnetic transfer includes a substrate having a concave portion formed in its surface corresponding to a pattern of recorded information to be transferred; a first perpendicular ferromagnetic layer deposited in the concave portion; and a second perpendicular ferromagnetic layer layered on the substrate surface and the first perpendicular ferromagnetic layer surface. The substrate surface and the first perpendicular ferromagnetic layer surface are flattened to form a single flat surface. In the master medium for magnetic transfer, a magnetic field change in a direction parallel to the substrate surface at a magnetization boundary of the first perpendicular ferromagnetic layer is steep. Since the influence of the change of an external magnetic field is reduced, it is possible to perform accurate transfer from the master medium for magnetic transfer to a slave medium for magnetic recording.

摘要： According to one embodiment, a magnetic disk apparatus includes a patterned disk, a slider, two read heads, a write head, and a drive circuit. The patterned disk has a magnetic recording surface on which bit patterns are arranged concentrically. The slider is located near the magnetic recording surface, and moves relatively to the magnetic recording surface. The read heads are arranged along a medium running direction at an end of the slider, and read magnetic data from the magnetic recording surface. The write head is located between the read heads, and records magnetic data to the bit patterns. The drive circuit drives the write head at a timing based on a period from when one of the read heads located upstream in the medium running direction reads magnetic data until the other located downstream reads the magnetic data at the same position on the magnetic recording surface.

摘要： A thermally assisted magnetic recording method includes the following steps. The recording layer of a magnetic recording medium is irradiated with a laser beam to produce a locally heated region. This heated region is moved by causing the recording layer and the laser beam to move relative to each other. To record desired information, a recording magnetic field is applied to the heated region of the recording layer. The laser beam has a cross section elongated in the direction in which the heated region is moved.

摘要： A magnetic recording medium includes a substrate and a recording layer formed on the substrate. The recording layer is provided with a plurality of information tracks each having a track servo signal region and a user data region. Adjacent information tracks are separated by non-magnetic material. The track servo signal region includes a plurality of magnetic portions arranged in a track-extending direction and non-magnetic portions interposed between the magnetic portions. The user data region includes magnetic portions arranged in the track-extending direction. The coercive force of the magnetic portions in the track servo signal region is different from that of the magnetic portions in the user data region. For instance, the former coercive force is weaker than the latter coercive force.
