    Abstract: A read-only recording medium and a reproducing method thereof ensures reproduction compatibility with a rewritable recording medium in which real data is recorded with substantial discontinuity. The read-only recording medium comprises a data recording area in which real data is stored; and a plurality of waste areas allocated at intervals in the data recording area. The method of reproducing data stored in a read-only recording medium reproduces data from the read-only recording medium, skips if a waste area is encountered or removes invalid data reproduced from the waste area wherein each waste area has been inserted periodically in the read-only recording medium, and outputs the data reproduced before and behind each waste area in succession. As a result, the playability is improved in a disk device capable of reproducing both a read-only and a rewritable recording medium.

    Abstract: An apparatus and method for detecting a defect in a wobble pattern using a wobble signal detected from an optical recording medium, by which verification is performed on a defective region if a defect is present in the wobble pattern when recording data on the optical recording medium. The apparatus for detecting a defect in a wobble pattern on an optical recording medium includes: a phase-locked loop (PLL)(101) that generates a phase-locked looped wobble signal and a wobble clock signal when a wobble signal from the wobble pattern is applied; a window signal generator (103) that generates a signal indicative of a wobble window period according to a predetermined window width condition when the phase-locked looped wobble signal and the wobble clock signal are applied; a wobble lock/unlock detector (105) that outputs a signal detecting one of wobble locked and unlocked states depending on predetermined wobble locked and unlocked conditions when the wobble window signal and the wobble signal are applied; and a wobble defect detector (107) that detects whether any defect exists in the wobble pattern depending on a predetermined defect decision condition when the signal detecting one of the wobble locked an unlocked states, the wobble window signal, and the wobble signal are applied. Accordingly, the apparatus and method allow a verification to be performed on data of a sector or a block where a defect of the wobble pattern occurs during a recording operation, thereby minimizing data loss caused by recording data on a defect region.

    Abstract: When an error-correcting code is created for the data stored in a memory (2) and added to the data, even if an error occurs in the data on the memory (2), the adverse effect of the error will be eliminated. In the present invention, when the data is stored in the memory (2), an error-correcting code PI is created beforehand using another memory (1), such as an S-RAM. The error-correcting code PI, together with the data, is written into the memory (2). After 16 sectors of data and PI have been stored, an error-correcting code PO is created for the data and PI and added to them. When the data is read from the memory (2), a PI correcting process is carried out each time a PI series is read out. This makes it possible to restore the original data, even if the data is destroyed (or an error occurs) on the memory (2).
