Abstract
An information recording medium that can be rapidly finalized, and a recording/reproducing apparatus and method using the same are provided. In the information recording medium, a prepit is pre-formed in a finalization area. Since the portion that has to be filled with data in finalizing the information recording medium is previously formed as the prepits series in manufacturing the information recording medium, the time necessary to finalize the information recording medium can be shortened, thereby achieving the rapid finalization of the medium.
Claims9
An information recording medium, comprising:
- a data area configured to store user data;
- a first middle area whose location is fixed, and which is configured to be embossed by a manufacturer;
- a second middle area which is variably positioned according to the amount of the user data to be recorded in the data area, and
- a predetermined area configured to store information indicating whether the first middle area is embossed,
- wherein when the information indicates that the first middle area is not embossed, data for finalization is recorded in the first middle area during finalization of the information storage medium, and
- wherein an outer circumference of the first middle area is adjacent to an unused area, an outer circumference of the unused area is adjacent to a buffer area, and an outer circumference of the buffer area is adjacent to a test area.
A recording/reproducing apparatus for recording data on an information recording medium or reproducing data recorded on the information recording medium, the recording/reproducing apparatus comprising:
- a write/read unit configured to record data on the information recording medium or to read data from the information recording medium comprising a data area configured to store user data;
- a first middle area whose location is fixed, and which is configured to be embossed by a manufacturer;
- a second middle area which is variably positioned according to the amount of the user data to be recorded in the data area, and a predetermined area configured to store information indicating whether the first middle area is embossed;
- and
- a control unit configured to:
- control the write/read unit to read information indicating whether the first middle area is embossed, from the predetermined area in the information recording medium;
- and
- control a data recording operation based on the information indicating whether the first middle area is embossed,
- wherein when the information indicates that the first middle area is not embossed, the control unit is configured to control the write/read unit to write data for finalization in the first middle area during finalization of the information recording medium, and
- wherein an outer circumference of the first middle area is adjacent to an unused area, an outer circumference of the unused area is adjacent to a buffer area, and an outer circumference of the buffer area is adjacent to a test area.
