Abstract
A reproduction apparatus is provided for use with a recording medium on which sub-data is recorded in association with main data. The apparatus includes a reading device for reading the sub-data from the recording medium, a memory for storing the sub-data, a data discriminator for determining whether a piece of sub-data read from the recording medium, which is at least one portion of the sub-data, is included in stored data already stored in the memory, and a controller. The controller stops the reading device from reading the sub-data when the data discriminator determines that the piece of sub-data is included in the stored data.
