摘要： A magneto-optical disc recording apparatus includes a magnetic head, an optical head, a position detector and a controller. The magnetic head supplies a vertical magnetic field corresponding to recording data to a magneto-optical disc. The optical head emits a light beam to the magneto-optical disc through a substrate of the magneto-optical disc. The magneto-optical disc is arranged between the magnetic head and the optical head. The optical head has an actuator for moving an objective lens in a tracking direction. The position detector detects the displacement of the actuator. The controller controls a recording operation of the magnetic head and the optical head. The recording operation is started when a result of detection by the position detector reaches a predetermined value.

摘要： A disc player for playing a first disc having data recorded on both sides thereof and also a second disc having data recorded on only one side thereof has disc drive means loadable with one of the first and second discs selectively. Whether the disc loaded on the drive means is the first disc or the second disc is detected from the data read by pickup means. When the second disc is detected, the pickup means is positioned for the data recording side of the second disc automatically so as to reproduce signals therefrom. Accordingly, even if the second disc is loaded with the disc side oriented erroneously, the data can be read from the recording side at all times.

摘要： A disk recording or playback device first sets a target region, and a pickup (3) is moved toward the disk inner periphery to turn on a sensor switch SW. The pickup (3) is thereafter reversely moved, and further caused to overrun for a predetermined period of time from the position where the sensor switch is turned off. The pickup (3) is returned after reading the address reached by overrunning. If the address is closer to the disk outer periphery than the target region, the overrun time is decreased, and the movement of the pickup (3) toward the lead-in area is repeated again. When the overrun time becomes not greater than a specified value and if the address then read is closer to the disk outer periphery than the target region, the direction of overrun is reversed toward the disk inner periphery. The overrun time enabling the pickup to reach the target region accurately is saved.

摘要： In a magneto-optical recording apparatus, light spots are successively formed on a magneto-optical disc (2) at a timing of a predetermined reference clock signal (S CK ), and record data are magnetically recorded onto the disc (2) by applying a predetermined modulation magnetic field (H M ) of which the polarity is inverted depending on the record data in synchronism with the reference clock signal (S CK ). At least one of the timing of irradiating a light beam (LA₁) forming the light spots, the light volume of the beam or the irradiation time is controlled depending upon the temperature of the disc (2) and/or the scanning position of the light spot, in order to form a pit (P) at a correct position relative to the timing of the reference clock signal (S CK ).
