Abstract:
1. A method of recording control information on a recording medium, comprising: generating respective control information units associated with at least first and second recording layers, each control information unit for a specific recording layer, a specific recording velocity and a specific write strategy usable at the specific recording velocity, the respective control information units including type information identifying a type of the corresponding control information unit and a write strategy information dependent on the type of the corresponding control information unit, wherein the type information indicates whether the corresponding control information unit 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 indicates the corresponding control information unit is usable for CAV mode, the corresponding control information unit 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 respective control information units on a specific area of the at least one of first and second recording layers.
