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.

摘要： The present invention relates to a magneto-optical recording medium having a recording layer on which data is recorded by irradiation with recording light and application of a magnetic field and being irradiated with recording light and supplied with a magnetic field on the recording layer side. An object of the present invention is to provide a magneto-optical recording medium that is capable of being irradiated with a high-power laser beam without increasing media noise during reproduction and a recording layer of which can be heated sufficiently with a moderate-power laser beam to reduce its magnetic coercivity during recording. The magneto-optical recording medium includes a substrate; a first heat-dissipation layer that is formed on the substrate and has a predetermined high thermal conductivity; a separation layer that is formed on the first heat-dissipation layer and has a low thermal conductivity lower than the high thermal conductivity; a second heat-dissipation layer that is formed on the separation layer and has a predetermined thermal conductivity higher than the low thermal conductivity but lower than the high thermal conductivity; and a recording layer that is formed above the heat-dissipation layers and on which data is recorded by irradiation with recording light and application of a magnetic field.

The tab includes a protrusion protruding inward. The bottom case includes a lower-side folded portion formed by folding inward an upper end of one side surface of the bottom case. The lower-side folded portion includes a cantilever spring. The cantilever spring includes a spring portion extending in a vertical direction and a curved portion formed by folding inward an upper part of the spring portion. The protrusion comes into contact with the curved portion when the top case is being affixed to the bottom case and is in contact with the spring portion under a state where the top case is affixed to the bottom case.
