Digital content management device and digital content management program

Abstract

When digital content is recorded, identification information for the digital content and a random number are recorded on each of a nonvolatile memory and an internal HDD. When the digital content is moved from the internal HDD to another recording medium, the random number recorded in the nonvolatile memory and the random number recorded on the internal HDD are compared to see if theymatch. Also, an offset value that indicates a location of a previous end-point at which the digital content has been ended to be read is read from the internal HDD, and the read offset value is compared with a location of a start-point at which the digital content is started to be read. If the random numbers match and the location of the start-point is greater than the offset value, the digital content is permitted to be moved.
