Abstract
A recording medium, and a method and apparatus for recording data in the recording medium are disclosed. The recording medium including an inner area, a data area, and an outer area includes a first test area contained in the inner area, and a second test area contained in the outer area, wherein the first and second test areas are formed by a predetermined wobble modulation method equal to that of the data area. Therefore, the recording medium can be applied to a method for manufacturing a Blu-ray disc, and data can be effectively recorded/reproduced in/from the recording medium, such as the Blu-ray disc.
Claims31
A recording medium including an inner area, a data area, and an outer area, comprising:
- a first test area contained in the inner area;
- and
- a second test area contained in the outer area,
- wherein the first and second test areas are formed by a predetermined wobble modulation method equal to that of the data area.
A method for recording data in a recording medium, comprising the steps of:
- (a) reading position information indicating available area of a test area assigned to an outer area of the recording medium, the position information being included in management information recorded in the recording medium, and recognizing a physical position corresponding to the read position information;
- (b) performing an Optimum Power Control (OPC) process for calculating an optimum write power in the recognized available area;
- and
- (c) recording data in the recording medium using the calculated optimum write power.
An apparatus for recording data in a recording medium, comprising:
- a pickup unit reading data recorded in the recording medium, the data including position information indicating available area of a test area assigned to an outer area of the recording medium, and the position information being included in management information recorded in the recording medium, and recording data in the recording medium;
- and
- a controller recognizing a physical position corresponding to the position information read from the pickup unit, searching an optimum write power by performing an Optimum Power Control (OPC) process in the recognized available area, and controlling the pickup unit to record data in the recording medium using the searched optimum write power.
