First Claim
1. A recorded media player including a media changer mechanism which addresses a current medium, and updates an internal memory by accessing a remote database, comprising in combination:
- a memory that stores additional information obtained from a local database, the additional information corresponding to a plurality of recorded media; and
a search engine which identifies the current medium using an identifier derived from information stored on the current medium, uses the identifier to search the local database to determine whether additional information about the current medium resides in the local database, and uses the identifier to search said remote database in the event the local database contains no additional information about the current medium.

Abstract
A method and apparatus for updating a memory in a Compact Disc changer. Information identifying discs stored in a CD changer is stored in a memory. The memory is updated when a CD is loaded which does not have identifying features which are recognized by the CD changer. Updating is carried out via a modem connection to a remote database. The database can be stored locally in a local database residing in a personal computer where the database can be queried to locate desired tracks and can be used to facilitate control of the compact disc changer by providing a simplified interface for building a play list and the like.
