Mastering compact disks and minidisks.

摘要

A mastering apparatus (FIG. 1) which can produce both of a format signal for a compact disk and another format signal for a minidisk is disclosed. Most of components of a mastering processing system for a compact disk are used commonly for another mastering processing system for a minidisk, and an address generator (30) 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 (26) 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. <IMAGE>
