Optical Recording Method and Apparatus

A method of recording a plurality of data units from a source via a buffer to an optical recordable medium, the method comprising:

• receiving a first number of data units from the source to the buffer;
• recording the first number of data units to the optical recordable medium;
• verifying a second number of data units being recorded on the optical recordable medium;
• releasing the second number of data units in the buffer when the second number of data units is verified;
• receiving a third number of new data blocks from the source at the released buffer space;
• and
• following to an initial position of the third number of recordable units to record the third number of data units after verifying the second number of data unit being recorded on the optical recordable medium.

An recording system for recording a plurality of data units from a source via a buffer to an optical recordable medium, the apparatus comprising:

• a pick-up head module (PUH module), for controlling a pick-up head to record a first number of data units to the optical recordable medium and to read a second number of data unit being recorded from the optical recordable medium;
• a verifier coupled to the PUH module, verifying the second number of data units being recorded and generating a verifying status signal;
• and
• a buffer management unit for controlling the buffer to buffer data units, and receiving the verifying status signal, when the verifying status signal indicating one of recorded data units is verified, generating a transfer control signal for receiving new data unit, and a buffer control signal to control the buffer to release buffer space of the verified data unit to buffer new data unit;
• wherein after the verifier verifies the second number of the data units, the PUH module controls the PUH to follow to an initial position to record a third number of new data units and keeps recording and reading until the plurality of data units being recorded and verified.
