Embodiment Construction

[0029] Embodiments of the recordable optical disc, its control information recording method, and the optical disc recording and playing method and device of the present invention will be described in detail below with reference to the accompanying drawings. To simplify the description, the case of a recordable Blu-ray Disc (BD-WO) will be described.

[0030] Corresponding to this, although the terms used in the present invention have selected the most widely used general terms, in specific cases, the terms selected by the authors themselves are also used. In this case, in the explanation part of the corresponding invention Its detailed meaning will be recorded, so it is not a simple term name, which needs to be further clarified by mastering the present invention.

[0031] In connection with this, among the terms used in the present invention, "recording control information" means information that can identify whether recording is permitted or prohibited for all or a part of a...

Abstract

The invention relates to a disc recorded for one time and its control information recording method and disc recording playing method and device, especially for the disc which is set definite space for continuous recording, it characterized in that separate recording decides whether the first record control information (WP_flag_TDDS) recorded in integral record range is forbidden and whether the second record control information (WP_flag_SRRI) recorded in every record range is forbidden. So whether the record and be supplied to definite recording range in disc and whether the logic overlap record can be proceed can be judged concretely, the disc can be used more efficiently.

Description

technical field [0001] The invention relates to a recording method for recording control information of an optical disc which can be recorded once, and a method and device for recording and playing the optical disc using it. Background technique [0002] As an optical recording medium, an optical disc capable of recording large-capacity data is being widely used. Among them, a new type of high-density optical recording medium ( HD-DVD), for example, Blu-ray Disc (BD: Blue-ray Disc) is being developed. [0003] As a next-generation HD-DVD technology, Blu-ray Disc (BD) can store far more data than existing DVDs. Currently, it is a solution for next-generation optical recording and has recently gradually become a world-standard technology. [0004] Various standards related to the Blu-ray Disc (BD) are being prepared, and following the Blu-ray Disc Rewritable (BD-RE), standards for the Recordable Blu-ray Disc (BD-R) are being planned. [0005] In particular, the disc recordin...
