Patent ID: 7496773

Claim:
A data recording and reproducing system including an optical disk apparatus which records and reproduces data with respect to an optical disk, the system comprising: a processor connected to the optical disk apparatus via an interface, for transmitting a command to the optical disk apparatus and receiving reproduced data from the optical disk apparatus, the processor including a rewritable non-volatile memory; key operation means; a key controller for interpreting a key operation signal generated by the key operation means and providing an instruction to the processor; a power source circuit for supplying a power source voltage to the optical disk apparatus, the processor, and the key controller, the power source circuit being capable of switching states between a voltage supply state and a voltage interruption state at least with respect to the processor; an input signal terminal; and an input signal detector for detecting that a signal is input from the input signal terminal and outputting the signal to the key controller; wherein when a predetermined video recording condition and a key operation signal “RECORD” are input form the key operation means: the key controller provides a predetermined video recording mode command to the processor; and the processor writes the video recording condition and the video recording mode command onto the rewritable non-volatile memory, and, when input of the signal is detected by the input signal detector, causes the power source circuit to return from the voltage interruption state to the voltage supply state and then supplies the signal to the optical disk apparatus and records the signal on the optical disk in accordance with the video recording condition and the video recording mode command which are stored in the rewritable non-volatile memory.
