    摘要: A disc drive device optimally controls a speed for reading RTR-format data, such as video and audio, recorded on a DVD-format disc, thereby enabling real-time playback without interruption. In the disc drive device, information added to each sector is used for determining whether data is RTR-format data. When an error occurs at high-speed reading of RTR-format data and therefore the reading speed is changed to a low speed, the reading speed is so controlled as to be kept at the low speed for reading the following RTR-format data. Thus, for RTR-format data, overhead due to repetitive acceleration and deceleration processes can be avoided, and reading can be carried out without interfering with real-time playback. For normal data, reading can be carried out in a manner similar to that in the background art.

    摘要: A disk reproducing apparatus and a disk reproducing method which permit continuous reproduction of data of the RTR type without interruption and without affecting real time reproduction.A defective block list with defective blocks and alternative blocks registered linked to each other by the types of defective blocks has been acquired beforehand from a recording medium and when there arises need to read a defective block, its alternative block is read out and forwarded to a reproduction requester. Here, reading control means identifies the type of defective blocks registered on the defective block list and controls the reading according to the identification results.
