    摘要: On a dielectric layer of SiN a reproduction layer, a non-magnetic layer of SiN and a recording layer of TbFeCo are formed to provide a magneto optical recording medium. The reproduction layer is formed of a first layer corresponding to a Gd layer, a second layer formed of GdFeCo and a third layer corresponding to a Gd layer. As such, the magneto optical recording medium, with the non-magnetic layer formed in contact with the reproduction layer, can prevent the non-magnetic layer from affecting the reproduction layer and thus prevent the reproduction layer from having a degraded characteristic.

    摘要: A magnetic head is configured of a core and a coil wound around the core and passing current through the coil in a variable direction allows the core to have an edge generating an alternating magnetic field Hex1 and another edge generating an alternating magnetic field Hex2. Alternating magnetic fields Hex1 and Hex2 are applied to the respective edges. Furthermore, a laser beam LB1 is directed such that its optical axis L01 matches the edge receiving the alternating magnetic field Hex1, and a laser beam LB2 is directed such that its optical axis L02 matches the edge receiving the alternating magnetic field Hex2. A first magneto-optical signal detected through the alternating magnetic field Hex1 and the laser beam LB1 and a second magneto-optical signal detected through the alternating magnetic field Hex2 and the laser beam LB2 are composited together. As such, an alternating magnetic field can be applied to a magneto-optical recording medium at a predetermined angle to an in-plane direction of the recording medium to accurately enlarge a magnetic domains for reproduction.

    摘要: When recording a recorded signal consisting of “01011001110” in a magnetooptical recording medium, (1,1) corresponding to a domain of 2T is converted to (1,0,1), and (0,0) is converted to (0,1,0) in the recorded signal. In other words, the first “1” of (1,1) is converted to unit bits “1,0” and the first “0” of (0,0) is converted to unit bits “0,1”. Similarly, the first “1” of (1,1,1) corresponding to a domain of 3T is converted to unit bits “1,0”, and the second “1” is converted to unit bits “1,0”. “1” or “0” of the final unit bit is not converted but recorded as such. Consequently, a signal can be correctly reproduced by extension ally transferring domains having different domain lengths from a recording layer to a reproducing layer under the same reproducing conditions.

    摘要: There is provided an optical disk drive capable of appropriately effecting recording and reproducing operations without being affected by offset values and a laser output value, which are set at startup of the disk drive, even when changes have arisen in the internal temperature of the disk drive because of changes in ambient temperature. In an optical disk drive, a temperature sensor provided on a pickup measures a temperature. When changes in temperature are greater than a predetermined level, a focus offset value, a tracking offset value, and a value of laser output from the pickup are reset.

    摘要: The present invention provides smooth and adequate recording/reproducing on a recording medium employing a biodegradable material as a substrate material. The present invention relates to storing on a recording medium, information, structure, or the like indicating that a substrate is formed of a biodegradable material. When the present invention is applied to CD, CD-R, and CD-RW, identification information indicating a substrate formed of a biodegradable material is included in a free area of TOC data in a lead-in area shown in FIG. 4. An optical disc apparatus reads the identification information to identify whether or not a disc loaded into the apparatus has a substrate of a biodegradable material. When the loaded disc has a substrate of a biodegradable material, the optical disc apparatus: measures a temperature inside a drive; stops a recording/reproducing operation on the disc when the temperature approaches a glass transition temperature of a substrate material; and ejects the disc to outside of the apparatus.
