    摘要: When user data is recorded on a write-once medium, linking variations can be reduced that are produced as management information for managing the user data is updated by additionally recording on and off, thereby assuring the reliability of the reproduction compatibility of the DVD player.Before the final file of the management information is recorded, dummy data of a plurality of successive blocks are recorded at a time by a single operation, and then the final file is additionally recorded after the dummy data. Therefore, the linking precision can be prevented from being degraded in the linking portions of the management information, and thus the management information can be properly read when the DVD player makes compatible reproduction of the medium.

    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: There is provided an optical disk apparatus that can inhibit, during recording or reproduction of data on or from an optical disk, a side runout that may occur in the optical disk in its circumferential direction as a result of Coriolis force when a disk rotating shift is subjected to procession movement, thereby allowing recording and reproducing quality to be stabilized and a reduced size of the apparatus. The disk apparatus provided has pressure pawls arranged at intervals smaller than those in the prior art, each of which is provided with a plurality of pressing points arranged at intervals larger than those in the prior art. Particularly, an interval between the pressure pawls is an acute angle in terms of the center angle of the disk. An interval between the pressing points is an angle of 35° or larger.

    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.
