• a second method of recording music on portable digital media at a retail premises, using the apparatus of Fig. 7, is as follows.
• the second method (Figs. 10A - 10C) is identical to the "pre-purchase method" with a single exception: the shopper would receive a free purchase card 230 used to consolidate all selected tracks into a single music compilation identified only by the unique barcode of the purchase card 230 used to select music tracks. At the end of the track selection, the shopper would need to pay for his selected music tracks and receive a flashcard 260 matching the capacity of total music selected. After paying for the music and the appropriate flashcard 260, the shopper could go to any preview station 214 and insert the flashcard 260 into the station 214 slot, scan the barcode of the purchase card 230 and the station 214 would begin the copying of the selected tracks to the flashcard 260 from the music memory 212.
• Scanning a unique barcode on the purchase card 230 allows the apparatus to keep track of all song selections and their originator/owner at any station. Linking each song to a single unique barcode provides logical means to organize all tracks and record a custom portable digital medium by each individual shopper.
• the shopper hands the purchase card 230 to the store clerk at the checkout counter.
• the store clerk scans the purchase card 230 at the main central station (which may simply be a preview station 214, and may be protected by a security code) and returns the card to the customer. Scanning the purchase card 230 provides the employee visual verification of the total number of tracks, total number of minutes recorded, total purchase price and the appropriate flashcard 260 required. If connected to the store's POS, flashcard recording, billing and receipt printing can be accomplished after the barcode of the purchase card 230 has been scanned at the checkout counter. While the above describes a retail music store application, the same might be applied to a bookstore or even a library to sample books on CD or tape.
