Patent ID: 6985416

Claim:
A method for optimizing performance of a read buffer and a write buffer in a disc media device having a feature requiring apparently simultaneous reading and writing where data is continuously added to said write buffer and continuously depleted from said read buffer, said method comprising: alternately writing data to said media from said write buffer during a write time t W and reading data from said disc media to said read buffer during a read time t R , said read time and said write time separated by a jump time t J , selectively controlling said write time so that it is approximately equal to 2 r 1 r 4 t J /(r 1 r 3 −r 1 r 4 −r 2 r 3 ): wherein r 1 is the front end read speed, r 2 is the decoding bit rate, r 3 is the front end write speed of said recordable media device and r 4 is the encoding bit rate.
