Abstract: PROBLEM TO BE SOLVED: To stabilize recording quality.SOLUTION: During an information recording operation on an optical recording medium, the recording operation is suspended at a predetermined time, and already-recorded part is regenerated to obtain an evaluation value of recording quality. Then, the recording operation is resumed upon changing a recording linear velocity based on determination of the recording quality using the evaluation value. For example, if a deterioration in quality is unacceptable, the recording linear velocity is decreased, or if there is no deterioration in quality, the recording linear velocity is increased.

SOLUTION: A sub-mount 30 is disposed between an LD bar 10 and a heat sink 20, and each of the LD bar, heat sink and sub-mount is joined by a first adhesive layer 40 and a second adhesive layer 50 composed of a solder or a gold (Au)-tin (Sn) solder. A first layer 31 in the sub-mount 30 has approximately the same coefficient of thermal expansion as the LD bar 10 in copper tungsten (CuW) or the like, and a second layer 32 has approximately the same coefficient of thermal expansion as the heat sink 20 in copper (Cu) or the like. The stress applied to the first adhesive layer 40 and the second adhesive layer 50 is reduced, and the reliability is improved. The first layer 31 and the second layer 32 are formed in an integral structure by a mutual joining by a soldering or a diffusion junction, and the stress by the difference of the coefficients of thermal expansion is absorbed surely on a firm junction interface.

Abstract: PROBLEM TO BE SOLVED: To prevent the generation of an error in reading time axis information from a wobble, and to prevent the incapability in reproducing information from an optical disk or the generation of a writing error, in an optical disk apparatus which records and/or reproduces information for the optical disk provided with the wobble including the time axis information. SOLUTION: Evaluation parameters such as a CRC error rate of an ATIP signal, an FMDT jitter amount, a phase error between an ATIP synchronized signal and a frame synchronized signal of recording data are evaluated with the standard of a set value range. When the parameter for the evaluation is out of the set value range, a recording/reproducing velocity is changed so that the reading quality of the wobble signal is elevated. COPYRIGHT: (C)2003,JPO
