Information-processing apparatus and information administration system using the same

摘要

Information-processing apparatus acquires unique identification (unique ID) from MiniDisc (MD) medium having an individual-information-recording area. Network server administers characteristic information of each of the MD media. The information-processing apparatus then acquires from the network server the characteristic information corresponding to the MD medium that has been identified according to the unique ID. The information-processing apparatus optimizes its servo characteristic according to the characteristic information to record or reproduce the information.
