  • Publication number: 20040141441
    Abstract: A disk-shaped recording medium recording/reproducing method for performing a data recording operation and a data reproducing operation to the disk-shaped recording medium alternately includes identifying whether a recording area at an ending point of an n-th recording operation on the disk-shaped recording medium, where n is a natural number, is continuous to a recording area at a starting point of (n+1) recording operation. In response to an identifying result indicative of discontinuation of the recording area in the identifying step, the rotational speed of the disk-shaped recording medium is changed to a rotational speed at the starting point of the (n+1)th recording operation, during a reproducing operation between the n-th recording operation and the (n+1)th recording operation.

  • Patent number: 6409141
    Abstract: A flow cell 2, a composite lens 15, and first to third detectors 16 to 18 are arranged in this sequence in the light pathway of light emitted from a laser light source 1. The composite lens 15 is configured by a convex lens 15a, and lens elements 15b and 15c. These lenses have different focal lengths. When the posture of the composite lens is correct, light impinging on the convex lens forms an image on the first detector. Therefore, the positioning of the composite lens is enabled. When particles in the flow cell are irradiated with laser light, forward scatter is produced. Forward small angle scatter having a small scattering angle impinges on the first lens element 15b to be collected thereby, and is then received by the second detector 17. Forward large angle scatter having a large scattering angle impinges on the second lens element 15c in the outermost periphery to be collected thereby, and is then received by the third detector 18 which is remotest from the composite lens.

  • Patent number: 6314542
    Abstract: 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.
