Embodiment Construction

[0041] figure 1 The data structure of the record carrier is shown.

[0042] The record carrier includes a track 1 with a lead-in area 10, 10a, 10b, a user data area 5, 6, 7, 9, a lead-out area 11, 11a, 11b, and a recording area indicator 2. The recording area indicator 2 includes an area 4 indicating the recorded data block on the record carrier and an area 8 indicating the data block still available for recording. Among the recorded data blocks of the recording area indicator, the recorded data block is indicated by '1' and the available data block is indicated by '0'.

[0043] The lead-in areas 10, 10a, 10b include mandatory information in the first part 10 of the lead-in area and the second part 10b of the lead-in area and optional information included in the reserved block 10a of the lead-in area.

[0044]When the recorder encounters a write error in the first or second part of the mandatory information, that is, the necessary data for retrieving data from the record carrier...

Abstract

When writing on recordable media, recorders may encounter write errors. When a writing error occurs, the record carrier is discarded. By ignoring writing errors in parts of the record carrier comprising unused information, such as lead-in or lead-out parts, it is no longer necessary to discard the record carrier.

Description

Technical field [0001] The present invention relates to a method for recording information on a record carrier in response to a format command or a close track dialogue command. The method includes the following steps: [0002] -Receive format commands or close track dialogue commands [0003] -In response to the format command or the close track dialogue command, write data blocks. [0004] This method can be known from the MMC310 standard NCITS XXX T10 / 1363-D. Background technique [0005] As an example selected from the MMC310 standard, the close track / dialog command allows the track or dialog to be closed. [0006] For CDs, closing the dialog will cause the lead-in and lead-out areas to be written for incomplete dialogs. Closing the dialog when closing the last dialog will not be considered an error. Closing the dialog when the last dialog was empty will not result in an action being executed and should not be considered an error. For example, for DVD-R / -RW and DVD+R / +RW, inc...
