  • Patent number: 8180197
    Abstract: A disk-like recording medium recording/reproducing method or apparatus for performing a data recording operation and a data reproducing operation to the disk-like recording medium alternately. The recording operation is performed at a constant linear velocity, and whether a recording area at an ending point of an n-th recording operation on the medium is continuous to a recording area at a starting point of an (n+1) the recording operation is identified. When a discontinuation of the recording area is identified, the rotational speed at the starting point of the (n+1)th recording operation is changed, during a reproducing operation between the n-th recording operation and the (n+1)th recording operation. When a continuation of the recording area is identified, the rotational speed of the disk-like recording medium at the ending point of the n-th recording operation is held, during a reproducing operation between the n-th recording operation and the (n+1)th recording operation.

  • Patent number: 6754442
    Abstract: A digital video or audio signal recording/reproduction method and apparatus and an optical disk apparatus are provided, in which a program is recorded in a recording medium on a disk while at the same time reproducing the video information already recorded. When the recording and reproduction are alternated repetitively, the rotation for recording is controlled in stable fashion. To this end, the rotation of the recording medium is controlled in accordance with the recording control method during the recording, and the rotational speed at the time of switching from the recording mode to the reproduction mode is held during the reproduction period, thereby stably controlling the rotation of the medium for recording.

  • Patent number: 6501718
    Abstract: Transfer of ancillary information, typically related to main information stored on an optical disk, to or from a storage on a disk is performed before the disk is capable of reproducing information. Described is a disk fitting aid member arranged in a recording and reproduction apparatus. Reproduction or recording of management information or catalog information for main information recorded or to be recorded is triggered by the operation of the fitting aid member. Alternatively, a recording and reproduction apparatus is mounted with a disk detector, with which the mounting of the disk on a tray can be detected, and the recording and reproduction of information to or from the storage is triggered by this detection.

  • Patent number: 6373799
    Abstract: An optical recording disk intended only for the reproduction of a main information and used by a information management system has the attachment of a memory in which data for the management of the main information is written and read out easily and reliably. The memory has associated electromagnetic coupling means for transacting the record management data with and receiving power from a recording/reproduction apparatus. The electromagnetic coupling means is built in the memory or disposed in an annular or spiral form on the disk. The transmission frequency band for data transaction and power supply is set outside the main information reproduction frequency band. The memory is disposed in or on an appropriate plastic layer of the disk depending on the usage of the disk, and located in the inner or outer section of the recording medium forming area on the disk depending on the transmission band. This low-cost optical disk can be manufactured at a high reliability and high yield.
