Abstract:
1. A disc access processor accessing a disc to read and write at least one of video data or audio data from and to the disc and processing a result of said accessing, comprising: differential calculation means calculating, before recording, a difference between said disc's temporal, maximum data recordable length and said disc's temporal length consumed by recording data; scale determination means determining a scale to allow a length of a period of a preprogrammed recording to be relatively matched on a timebase bar with a temporal length of said difference obtained by said differential calculation means; shortage calculation means calculating an amount of shortage of said temporal length of said difference relative to said length of said period of said preprogrammed recording; and image creation means creating an image for display, said image creation means including bar image creation means creating an image of said timebase bar, and wherein the image indicates the amount of shortage on the timebase bar on the scale allowing the length of the preprogrammed recording to be relatively matched with the temporal length of the difference.
