摘要：
A method and apparatus for recording data in a recording medium are disclosed. The method for recording data in a recording medium including a wobble-shaped test area includes the steps of a) determining a pre-used test area, b) searching for a current OPC start position of the test area by counting the number of wobbles at a wobble-count reference position, c) performing an Optimum Power Control (OPC) process to calculate an optimum write power at the OPC start position, and d) recording data in a data area using the calculated the optimum write power. Therefore, the recording medium can be applied to a method for manufacturing a BD, and a disc test process and data recording/reproducing operations can be effectively performed.
