Abstract
An information recording apparatus includes a recording medium receiver to receive a recording medium whereon information may be recorded by the apparatus and a non-volatile memory to store management information about the recording medium provided in the recording medium receiver. The management information provides information about whether or not data can be recorded on the recording medium.
Claims20
An information recording apparatus, comprising:
- a recording medium receiver to receive a recording medium whereon information may be recorded by the apparatus;
- and
- a non-volatile memory to store management information about the recording medium provided in the recording medium receiver, wherein the management information provides information about whether or not data can be recorded on the recording medium.
An optical disk apparatus, comprising:
- a receiver to receive an optical disk;
- a non-volatile memory space to store management information about the optical disk, the management information providing information about whether or not information can be recorded on the optical disk;
- a microprocessor to retrieve the management information by accessing the optical disk and store the retrieved management information to the non-volatile memory space;
- and
- a memory device to record information therein while the apparatus is not ready to record information on the optical disk.
A method for operating an information recording apparatus, the method comprising:
- retrieving management information relating to a recording medium provided in the recording apparatus;
- and
- storing the management information in a non-volatile memory, the management information providing information on a condition relating to recording video information to the recording medium.
A method for operating an optical disk apparatus, comprising:
- performing a recognition process upon turning on the apparatus;
- recording image data into a temporary memory space while performing the recognition process;
- and
- determining whether or not image data can be recorded on an optical disk provided in the apparatus using management information stored in a non-volatile memory device.
A digital versatile disc (DVD) apparatus, comprising:
- a receiver to receive a DVD disk;
- a non-volatile memory to store management information about the DVD disk, the management information providing information about whether or not image information can be recorded on the DVD disk;
- a microprocessor to retrieve the management information by accessing the DVD disk and store the retrieved management information in the non-volatile memory;
- and
- a semiconductor memory device to record image information therein while the apparatus is performing a recognition process,
- wherein the image information stored in the semiconductor memory device is transferred to the DVD disk after completing the recognition process using the DVD disk.
