Patent ID: 7372787

Claim:
An optical disc recording apparatus comprising: a recording unit which operates to record in a first mode and a second mode, wherein in the first mode, the data to be recorded is encoded to generate a laser diode driving signal, and in the second mode, the data to be recorded is bypassed without being encoded to generate a laser diode driving signal; a pickup unit, which responds to the laser driving signal and forms information coded on the disc during a recording process; and a buffer memory, which is disposed outside the recording unit, stores the data to be recorded that is input from a host computer through an interface with the recording unit, and outputs the data to be recorded to the recording unit, wherein the recording unit comprises a first encoder, which accesses the buffer memory through the interface, first encodes the data to be recorded to generate first encoded data and outputs the first encoded data in the first mode, and bypasses without encoding and outputs the data to be recorded in the second mode.
