SummaryDescription of the Minidisc mastering process.
AbstractA mastering apparatus which can produce both a format signal for a compact disk and another format signal for a minidisk. Most of the components of a mastering processing system for a compact disk are common to a mastering processing system for a minidisk. An address generator for generating an address upon mastering processing for a minidisk is provided. The operation condition of the address generator is controlled by controlling a digital signal processor of the address generator. When a compact disk format signal is to be produced, the address generator is controlled to a no-operation mode so that the apparatus operates as a compact disk mastering apparatus. On the other hand when a minidisk format signal is to be produced, the address generator is controlled to an operation mode so that the apparatus operates as a minidisk mastering apparatus.
