摘要： Using MSR (magnetically induced super-resolution) technology, a read-head field is applied to a magneto-optical recording medium when reading an information signal from a recording layer of a magneto-optical recording medium, in order to magnetize the read light-irradiated magnetic layer in one direction in a part of an area within the read light spot. The magneto-optical recording medium using MSR technology adopts the on-land recording method in which an information signal is written to the land, which enables read of an information signal by the MSR technology with a smaller read-head field.

摘要： A magneto-optical disk having recording tracks are formed along concentric grooves or a spiral groove. A non-groove region where no grooves are made is provided in a middle part of each recording track. In the non-groove region, there is formed a pit pattern representing information about the recording track. A track-counting U-groove is formed in the non-groove region, for detecting that the light spot of a reading laser beam has moved across the recording track. With the disk thus structured, it is possible to record information at high density and to access a desired recording track at high speed.

摘要： A magneto-optical recording medium (D1) includes a soft magnetic layer (2) and a magneto-optical recording layer (3) laminated sequentially onto a substrate (1) and is provided with a plurality of grooves (G) and lands (L). The product of the saturation magnetic flux density and thickness of the soft magnetic layer (2) is made different for the respective grooves (G) and lands (L). Thus, with respect to each groove (G) and each land (L), the magnetic focusing effect can be enhanced for one of these with a greater product of saturation magnetic flux density and thickness of the soft magnetic layer (2), while the effect can be weakened for the other one with a smaller product of saturation magnetic flux density and thickness of the soft magnetic layer. This enables the incidence of cross-writing to be suppressed.
