Abstract
Data recording and reproduction systems, apparatus, and methods provide efficient recording of and reproduction from storage media having multiple surfaces. In particular, a grouping processing unit groups data based on several factors. The grouped data can then be efficiently stored on storage media having multiple sides to increase the efficiency of storage and retrieval of such data. For example, data belonging to the same group is not stored on two surfaces of the same storage media to avoid having to remove and reverse the direction of the storage media in order to store data on or retrieve data from the other side of the storage media.
