Patent ID: 7725649

Claim:
A method of recording record signals sequentially transmitted from a host on an optical recording medium, the method comprising: receiving record data sequentially transmitted from the host and storing the received record data in a buffer if a predetermined environment for a data recording apparatus on the optical recording medium to record the received data is set; building table of contents information using the record data to be recorded in a lead-in region of the optical recording medium among the record data stored in the buffer, wherein the building table of contents information includes; for a first block type of the record data, identifying a number of blocks if a 16 byte-SubQ value exists among the record data stored in the buffer, interpreting a SubQ value of each of the identified blocks, and building the information on the optical recording medium using an index value in the interpreted SubQ value of each of the identified blocks; and sequentially recording the data in a raw recording mode on the lead-in region, a program region, and a lead-out region of the optical recording medium.
