    摘要: In an optical disk apparatus, by obtaining the temperature in the vicinity of a laser in the apparatus, the power source voltage of the laser driver is controlled such that power consumed by the headroom of the laser driver is reduced to the maximum extent without deteriorating the current drive characteristic of the headroom when the temperature becomes higher. The laser driving current of the laser driver is monitored to control the power source of the laser driver such that the power consumed by the headroom is possibly reduced while maintaining the current drive characteristic of the headroom for the monitored current.

    摘要: In playing back data in an optical disk device, to perform high-speed data playback with a low number of playback retries even if an error occur when data is being read. In reading data composed of ECC blocks, if a data error occurs during a read operation, the data from sectors for which PI error correction can be performed is left alone. Playback retries using different playback conditions are performed just on the sectors for which PI error correction can be performed. Thus, the playback retry count can be reduced.

    摘要: In a system recording compressed video and audio signals or computer user data on a disk in the sector unit, to reproduce the data in a simple fashion at a high speed, data to be recorded on the disk is divided into data in a predetermined unit so as to add a first error correction (C1) code to each of the resultant data, which form (C1) correction blocks. Sectors are produced each including a plurality of (C1) correction blocks. Added to each (C1) correction block is a code enabling identification of a sector. To all data in the plural (C1) correction blocks, a second error correction (C2) code is added to record the resultant data on the disk to allow interleaving or deinterleaving completing in a block. The capacity of each sector is set to be substantially equal to that of a plurality of transport packets.

    摘要: In a 360-degree toothbrush in which a brush head is formed by superposing disk-shaped radial vanes 1 in an axial direction, the arranging pitch of the radial vanes 1 is increased so as to make the bristle density appropriate. Spacers are not used between the radial vanes 1 so as to increase the productivity, and to improve the hygiene condition. In order to realize these aspects, an annular protrusion or protrusions 3 are formed on one or both of the surfaces of an annular weld portion 2 of the radial vane 1. The annular protrusion 3 is formed at the same time when forming the weld portion 2 in a welding step in which the bristle bundle is opened radially and the center part is welded so that the radial vane 1 is manufactured.
