Digital data recording method and digital data recording apparatus

An optical disk drive for time-divisionally recording digital data of a plurality of channels which is transferred from a host and in which real-time streaming performance is required in recording and reproduction onto an optical disk, comprising:

• an interface for receiving control data and user data from an external host;
• a signal processing circuit for signal-processing the data inputted from the interface;
• an optical head for recording the data onto the optical disk;
• a servo for controlling rotation of the optical disk;
• and
• control means for controlling the interface, the signal processing circuit and the servo,
• wherein the control means reports a recording condition determined in compliance with a recording condition included in the control data sent from the external host to the external host.

• an optical head for recording the data onto the optical disk;
• a servo for controlling rotation of the optical disk;
• and
• control means for controlling the interface, the signal processing circuit and the servo,
• wherein the control means sets a defect area that is not suitable for recording the digital data in which the real-time streaming performance is required in the recording and the reproduction in compliance with the control data sent from the external host and sets a plurality of recording areas each of which does not include the defect area into the optical disk.

An AV recorder comprising:

• an optical disk drive for time-divisionally recording digital data of a plurality of channels in which real-time streaming performance is required in recording and reproduction onto an optical disk;
• and
• a host for transmitting the digital data of the plurality of channels to the optical disk drive and controlling the optical disk drive,
• wherein the host sets a defect area that is not suitable for recording the digital data in which the real-time streaming performance is required in recording and reproduction and sets a plurality of recording areas each of which does not include the defect area into the optical disk.

An AV recorder comprising:

• and
• a host for transmitting the digital data of the plurality of channels to the optical disk drive and controlling the optical disk drive,
• wherein the host sets a recording condition into the optical disk drive, the optical disk drive reports the recording condition determined in compliance with the recording condition to the host, and the host controls the optical disk drive in compliance with the recording condition reported from the optical disk drive.

An AV recorder comprising:

• an optical disk drive for time-divisionally recording digital data of a plurality of channels in which real-time streaming performance is required in recording and reproduction onto an optical disk;
• and
• a host for transmitting the digital data of the plurality of channels to the optical disk drive and controlling the optical disk drive,
• wherein the host sets a recording condition into the optical disk drive, and when the recording under the recording condition is impossible, the optical disk drive reports information showing that the recording under the recording condition is impossible to the host.
