摘要:
The present invention provides a method of configuring and recording control information on an optical disc, thereby enabling to facilitate to utilize the specified control information and to efficiently cope with the recording/reproducing of the optical discs. In configuring a control information within a disc management area of a read-only or recordable disc, the present invention includes configuring the control information with a common field recording an information commonly applied to both of the read-only and recordable discs and a specific field recording an information failing to be commonly applied to at least one disc type.

One embodiment includes providing control information, wherein the control information includes one or more recording speed flags indicating respectively whether one or more recording speeds are applicable to each of the recording layers. The control information also includes write strategy information depending on each of the applicable recording speeds, and the control information is recorded on a specific area of the recording medium.

A recording medium, such as a high-density and/or read-only recording medium that has the same or similar physical recording format, including a linking area, in order to improve reproduction compatibility with a high-density and/or rewritable recording medium, and to methods and apparatuses for forming, recording, and reproducing the recording medium.
摘要:
In one embodiment, the method includes reading control information including version information from a specific area of the recording medium. The version information includes a first version information and a second version information. At least one of the first version information and the second version information is used to determine a backward compatibility with respect to reading or writing of the recording medium. A recording/reproducing of data on/from the recording medium is controlled based on the version information.
摘要:
A recording medium, and a method and apparatus for recording/reproducing data in/from the recording medium are disclosed. The recording medium includes one or more recording layers, and a management area including management information, wherein the management information includes specific information indicating a presence of different format and type of recording layer in the recording medium. The management area is located at a specific recording layer. The format represents a different category in a recording layer and the type is classified by read-only or writable in a recording layer.

A high-density optical disc such as BD-RE (Blu-ray Disc Rewritable) or BD-ROM, and a recording/reproducing method thereof are disclosed. Diverse additional information such as disc reflectivity information, disc layer information or disc type information is efficiently recorded in a particular information field included in a data unit recorded on the burst cutting area of a high-density optical disc or a particular 1-byte address field included in an address unit recorded on the high-density optical disc so that it can be read when the high-density optical disc is loaded in an optical disc apparatus or when a data recording or reproducing operation for the high-density optical disc is carried out. Accordingly, it is possible to achieve optimal optical power control and automatic gain control or identification of a current position, while enabling a normal data recording or reproducing operation corresponding to the type of the optical disc.

According to an embodiment, the invention is directed to an optical disc having signal tracks including a groove track, in which wobble signals are recorded on at least the groove track. Wobble units of wobble signals are modulated on the groove track, while at least 4 wobble units are used to represent a data bit of “0” or “1” in address information. Data bit of “0” or “1” in address information has a same phase and different phase with regard to alternate data bit at least to distinguish from each other.
摘要:
A recording medium, and a method and apparatus for recording data in the recording medium. The recording medium including an inner area, a data area, and an outer area includes a first test area contained in the inner area, and a second test area contained in the outer area, wherein the first and second test areas are formed by a predetermined wobble modulation method equal to that of the data area. Therefore, the recording medium can be applied to a method for manufacturing a Blu-ray disc, and data can be effectively recorded/reproduced in/from the recording medium, such as the Blu-ray disc.
摘要:
A high-density multi-layer optical disc, a method for recording data thereon on a layer-by-layer basis, and a method for managing spare areas thereof. In a high-density multi-layer optical disc, having a plurality of recording layers formed thereon, such as a Blu-ray disc rewritable (BD-RE) dual layer, management information is recorded and managed appropriately to the multiple layers so that data can be recorded in a state where the recording layers are linked to each other or the recording layers are separated from each other. Inner and outer spare areas are separately assigned to each of the recording layers formed on the high-density multi-layer optical disc. The management information is recorded and managed appropriately to the multiple layers so that the data can be recorded in a state where the spare areas of the recording layers must be used together irrespective of the recording layers or used separately on the layer-by-layer basis. The recording layers can be effectively used and managed, and the spare areas separately assigned to the respective recording layers can be effectively used and managed.
