Abstract
A method of data management for efficiently storing and retrieving data in response to user access requests. The method includes receiving a request from at least one client for a title not resident in a storage server, where the title includes a play track having a plurality of chapters, and then initiating retrieval of play track portions proximate chapter delineation points from a secondary storage device. In a case of a client request to begin presentation of the title at one of the chapters, the retrieved portions of the play track chapter are streamed to the client, while unretrieved portions of the play track chapter and subsequent play track portions are retrieved from the secondary storage device.
