摘要： A disk-like information recording medium includes recording areas provided in both of a groove portion and a land portion. The information recording medium is divided into groups of a plurality of areas, each track is divided into circular arc-shaped sectors having the same central angle arranged to be radial in the radius direction, identification information is provided at every sector, each track is divided into groups in such a manner that lengths of the circular arc-shaped sectors become almost constant among the groups, and the groove portion and the land portion are wobbled in the radius direction of the information recording medium. When the groove portion information track and the land portion information track which are the recording portions are wobbled in the radius direction, position information can be reliably obtained from the recording portions, and hence recorded information can be accessed reliably. Also, an accuracy with which the rotation of the information recording medium is controlled can be raised, and it becomes possible to position recorded information accurately.

摘要： An optical disk device which improves the S/N ratio of reproduced signals and increases the recording density on it. Pulsed reproducing light is projected onto the data detection points on the optical disk medium to reproduce the data. This enables the reproduction of signals of large optical intensity without raising the temperature of the recording layer. A servo region is irradiated with DC light to form channel clocks from the PLL.

摘要： An optical disc apparatus capable of restraining thermal deformation of an optical disc due to transmission of a heat from a spindle motor to the disc, comprises a turn table rotated by the spindle motor, for holding the disc, a bearing portion provided in the spindle motor, for holding a rotary shaft of the table, and a cooling element provided at the outer periphery of the bearing portion, for thermoelectrically cooling the bearing portion. The bearing portion can be directly cooled by the cooling element. Since the heat from the spindle motor is transmitted to the table through the bearing portion, the heat generated from the motor can be prevented from being transmitted to the table by cooling the bearing portion, and further, the table can be cooled. Thus, no heat is transmitted from the table to the optical disc, thereby thermal deformation of the optical disc can be retrained.

摘要： An optical recording apparatus having a light source and an optical system. The medium is a substrate in the form of a substantially circular disk with grooves and lands alternately formed on the substrate in a radial direction. The grooves and lands both serve as recording tracks which are divided into recording units in a circumferential direction. Each recording unit has an address area devoid of the grooves including first and second address information. The first address information is formed on a first boundary between one track and an adjacent track on one side of the one track, and the second address information is formed on a second boundary between the one track and an adjacent track on an other side of the one track with the first address information and the second address information not existing at opposing positions on the boundaries of the one track.

摘要： Because a series of data is recorded continuously, the recording quality of data recorded in course of recording cannot be evaluated. Accordingly, the laser output cannot be controlled properly and there are a deterioration and dispersion of the recording quality. Further, when the recording lasts for a long time, the temperature in the vicinity of laser rises due to the heat from the inside of a disc drive and the recording quality is deteriorated. To solve this, a series of data to be recorded is split and recording is made intermittently in a split data unit. The recording quality is evaluated by reproducing the data recorded nearby before each split data is recorded using a duration and control is performed by reflecting the evaluation result in the laser output so that the recording quality can be maintained satisfactorily over a series of the whole data to be recorded. Further, control is performed so that good recording quality can be maintained even in the recording that lasts for a long time by stopping the function of each part that ought to be operated even at recording or reproduction inside the disc drive in the duration, thereby suppressing a temperature rise.
