Optical disc apparatus
First Claim
1. An optical disc apparatus which records data on a CD-R or CD-RW data recording media, comprising:
- a decoder which carries out error correction;
pausing means which pauses a recording operation; and
restarting means which restarts the recording operation and links data at an end position where the recording operation is paused and data at a start position where the recording operation is restarted, such that data recorded at said start and end positions can be error corrected and reproduced; and
wherein said pausing means pauses the recording operation without writing a run out block.

Abstract
An optical disc apparatus includes a pause circuit for pausing data encoders upon receiving a pause signal so that a write operation may be paused without writing dummy data, thereby maintaining data succession. The optical disc apparatus also includes a circuit for accurately determining a write start location by referring to previously written data. A processor generates a pause signal when the amount of data in the optical drive apparatus data buffer is low, and removes the pause signal when additional data from a host is received. The processor may also automatically reduce the write speed of the optical disc apparatus upon a pause condition, thereby preventing the necessity for excessive pausing.

7. A device for recording data on an optical recording media, said device comprising:
-
a decoder for carrying out error correction; a pause circuit for pausing a recording operation; and a restart circuit for restarting the recording operation such that data at a start position where the recording operation is restarted is linked to data at an end position where the recording operation is paused, such that data recorded at said start and end positions can be error corrected and reproduced; and wherein said pause circuit is arranged to pause the recording operation without writing a run out block. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method of recording data on an optical recording media, said method comprising the steps of:
-
pausing a recording operation without writing a run out block; and subsequently, restarting the recording operation such that data at a start position where the recording operation is restarted is linked to data at an end position where the recording operation is paused, such that data recorded at said start and end positions can be error corrected and reproduced. - View Dependent Claims (14, 15)
