Optical disc apparatus
DCFirst Claim
1. An optical disc apparatus which records data on a CD-R or CD-RW data recording media, comprising:
- a pausing means which pauses a recording operation; and
a restarting means which restarts the recording operation and maintains data succession between an end position where the recording operation is paused and a start position where the recording operation is restarted; 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.
