Abstract: The present invention aims to smoothly and adequately adjust recording laser power while an increase in processing load during recording is suppressed. When a recording operation start request is received, OPC is executed with reference to a target ? value (?t) of a disc to set recording laser power Pws. Recording operation is performed based on the set recording laser power Pws. When a system is brought into an intermittent standby state, R-OPC is executed, so the recording laser power Pws is adjusted and set again. Then, its subsequent recording operation is performed based on the recording laser power Pws which is set again. When a duration of the recording operation exceeds a maximal waiting time Ts, the recording operation is suspended so that the system is set to a recording standby state. Then, the R-OPC is executed, so that the recording laser power Pws is adjusted and set again.

Abstract: A substrate in which a minute ruggedness structure including columnar projections is formed in a track shape is prepared. The pitch of the columnar projections of the ruggedness structure is set such that a plurality of the columnar projections is within a beam spot. A flat portion is disposed between adjacent tracks. A reflecting layer is formed on the substrate. The flat portion becomes a mirror surface because of the formation of the reflecting layer. The reflectance of the ruggedness structure becomes significantly lower than the reflectance of the flat portion. When the ruggedness structure is irradiated with high-power laser light, a portion of the ruggedness structure is raised to a reflecting layer side and flattened. At this time, reflectance of the raised portion becomes higher than reflectance of a non-raised portion. When a track including the ruggedness structure is irradiated with high-power pulse laser light, signal recording based on a change in reflectance is possible.

Abstract: Provided is an optical disc device in which adjustment precision of recording laser power is improved without complication of a processing sequence during recording operation. In response to a recording start instruction, OPC is executed using an inner disc drive zone to set an initial value of recording laser power Pws. Then, when a first recording instruction REC(1) is detected, recording is successively performed from the head of a data area using the laser power Pws. After that, when an intermittent standby period is set, sample data is recorded to a next recording position and R-OPC is executed. Therefore, the recording laser power Pws is set again. Next, when a second recording instruction REC(2) is detected, recording is successively performed from a next recording position, that is, a position next to an end portion of the first recording instruction REC(1) using the reset laser power Pws.

Abstract: To provide a magneto-optical recording medium and a layer structure with which it becomes possible to effectively achieve an increase of a Kerr rotation angle and improvements of a recording sensitivity and a recording density by using a simple construction. A minute ruggedness structure is formed on a substrate and a magnetic layer is formed thereon. The ruggedness structure is reflected in the magnetic layer. With the reflected ruggedness structure, multiple reflection occurs to reproduction laser light. When multiple reflection occurs to reproduction laser light, a Kerr rotation action is superimposed each time reflection is repeated at the magnetic layer. As a result, an increasing effect on a Kerr rotation angle with respect to the reproduction laser light is expected. Also, with the ruggedness structure reflected in the magnetic layer, the surface area of the magnetic layer is increased. Therefore, temperature rise of the magnetic layer by laser light irradiation is promoted.

Abstract: A mark level (peak value) is obtained from an RF signal during recording and the mark level (peak value) is divided by a linear value proportional to a recording power to obtain a normalized peak value. The obtained normalized peak value is compared with a target value to adjust a set value of the recording power. The normalized peak value, which is obtained by dividing measurements of the mark level (peak level) by the linear value for normalization, monotonously decreases along with an increase in the laser power. Therefore, the shift direction of the recording power can be detected based on the normalized peak value. Further, a shift of the recording power can be appropriately detected based on the normalized peak value level because a change in the normalized peak value level in a power margin range is relatively large.

Abstract: An object of the present invention is to further increase the speed of tilt control while suppressing a useless tilt control operation. Values of focus bias voltages (reference bias values V1 to V6) at a plurality of radial positions P1 to P6 are obtained and stored using a reference disk with a high flatness precision. Prior to a recording and reproducing operation, the values of focus bias voltages (Fo bias values vs1 to vs6) at the radial positions P1 to P6 are obtained, and each of tilt amounts T1 to T6 at the respective radial positions is obtained from a differential value between the reference bias value and the Fo bias value at each radial position. During recording/reproduction, a radial position Pn placed immediately before the recording/reproducing position is detected. Then, tilt control is performed with a tilt amount Tn at the radial position Pn being set as the tilt amount at the recording/reproducing position.

Abstract: A magneto-optical disk apparatus generates magnetic field onto a magneto-optical recording medium prior to recording signals in the magneto-optical recording medium having a recording layer and a reproduction layer, by use of magnetic field and laser beam. The magneto-optical apparatus then adjusts a position of a magnetic head that generates the magnetic field, under a state where the laser beam is irradiated, by utilizing that an irradiation spot of the laser beam deviates due to eccentricity of the magneto-optical recording medium. This position adjustment is carried out based on, for example, a beam position signal showing the irradiation spot of the laser beam and/or a detection signal which is detected after the laser beam is modulated by the magnetic field.

When a laser beam is irradiated to the magneto-optical recording medium, a magnetic domain in a recording layer is transferred, through enlargement, to a reproducing layer increased in temperature. The magneto-optical recording medium further includes a calibration area that has a calibration magnetic domain recorded in a predetermined pattern in the recording layer. In a reproducing apparatus, a laser beam of an optical head is adjusted in output depending upon a reproduced signal obtained by reproducing the calibration magnetic domain.
