Patent ID: 7817514

Claim:
A method of recording control information on a recording medium, comprising: generating a control information associated with at least one recording velocity, each control information is for a specific recording layer, a specific recording velocity and a specific write strategy usable at the specific recording velocity, the control information including type information identifying a type of the corresponding control information and a write strategy information dependent on the type of the control information, wherein the type information indicates whether the control information is usable for CLV (constant linear velocity) mode or CAV (constant angular velocity) mode, the write strategy information including write strategy parameters associated with CLV mode or CAV mode, wherein when the type information identifies the control information is usable for CAV mode, the control information includes information of at least three linear recording velocities and the write strategy information associated with the at least three linear recording velocities to be usable for performing the recording of data based on the CAV mode; and recording the control information on a specific area of the recording medium.
