摘要：
The present invention relates to a recording and/or reproduction apparatus and a program suitable for use to record or reproduce data onto or from an optical disk having two recording layers on one side thereof.
In an optical disk which has, on one side thereof, two layers including a recording film L0 layer in an unformatted state and another recording film L1 layer in a formatted state, the recording film L0 layer is formatted with marks at step S1, and formation of marks corresponding to recording data is started beginning with the recording film L0 layer at step S2. After the recording film L0 layer is used up, marks corresponding to recording data are formed on the recording film L1 layer at step S3. The present invention can be applied, for example, to a DVD player.
