Abstract

Disclosed is an video/audio player/receiver with an integrated digital recorder that improves over conventional digital audio or video playback devices commonly found in automobiles and the like. The present invention improves over conventional car audio technology by providing an otherwise conventional CD player for automotive use with a built-in magnetic media hard drive of a capacity sufficient to store the music of several CDs. By storing a variety of chosen individual songs or entire CDs on hard drive they are ready for instant playback, eliminating the need to carry several CDs and their cases, while still allowing the users to have their favorite songs at their fingertips.
