Optical disc apparatus
First Claim
1. A method of recording on an optical disc recording media, said method comprising the steps of:
- transferring stored input information from an input buffer to an encoder;
transferring encoded information from said encoder to a record circuit;
causing said input buffer to contain less than a threshold amount of said input information; and
when said input buffer contains less than the threshold amount of said input information, pausing said transferring of said encoded information, to stop said record circuit at a first point on said optical disk recording media while maintaining said encoded information within said encoder.

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.

10. A method of recording on an optical disc recording media, said method comprising the steps of:
-
transferring stored input information from an input buffer to an encoder; transferring encoded information from said encoder to a record circuit; causing said input buffer to contain less than a threshold amount of said input information; when said input buffer contains less than the threshold amount of said input information, pausing said transferring of said encoded information, to stop said record circuit at a first point on said optical disk recording media while maintaining said encoded information within said encoder; and when said input buffer contains at least the threshold amount of information, resuming said step of transferring said encoded information to said record circuit, to thereby restart said record circuit while maintaining data succession across said first point on said optical disc recording media.
