Embodiment Construction

[0029] Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like numerals refer to like parts throughout. The present invention will be described below in order to explain the present invention by referring to the figures.

[0030] Figure 1A shows a single recording layer write-once disc, Figure 1B A dual recording layer write-once disc is shown. In each data area, when a defect occurs in the user data area, a spare area is arranged to record data to be recorded in the user data area. Figure 1A and 1B The arrow shown in the data area in indicates the direction of use of the user data area.

[0031] figure 2 is a diagram showing the structure of a recording layer of a single recording layer write-once disc or a first recording layer L0 of a dual recording layer write-once disc, image 3 is a diagram showing the structure of the second layer L1 of the dual recording layer...

Abstract

A data recording and / or reproducing device for recording data recording status information on an optical disc and its optical disc. In an optical disc, a data area is divided into a plurality of sub-data areas, a record map including a plurality of record map entries is recorded in a predetermined area arranged on the optical disc, each record map entry includes a sub-data area in the plurality of sub-data areas location information and recording status information of the sub data area. In an optical disc, more detailed information on the recording status of data is recorded, so that a drive or a host receiving more specific and precise status information can efficiently use the recording space of the disc.

Description

technical field [0001] The present invention relates to a data recording and / or reproducing apparatus for recording data recording state information on an optical disc and an optical disc thereof. Background technique [0002] In conventional techniques, when user data is recorded on a write-once disc in which data can be recorded only once, the data area arranged on the write-once disc is divided into a plurality of sub-data areas, and user data is recorded in each on the subdata area. Furthermore, in order to indicate the data recording status in the data area of ​​the write-once disc, a record map is recorded in a predetermined area of ​​the write-once disc. [0003] A record map includes a plurality of record map entries. A record map entry includes a start address of a sub data area among a plurality of sub data areas included in the data area, and a last recording address (LRA) on which user data is last recorded. [0004] Each sub data area ...
