Master disc recording apparatus and method for recording data on different types of master discs

A master disc recording system for recording data on master discs of a plurality of different types, comprising:

• a plurality of intermediate recording media for storing data;
• a plurality of editing units for storing the data on a corresponding plurality of the intermediate recording media at a first transfer rate, each of said editing units storing data for a different type of said master discs;
• a plurality of reproducing units, corresponding in number to the plurality of editing units, for reading the data from the intermediate recording media at the first transfer rate and outputting the data at a second transfer rate, which is different than the first transfer rate;
• and
• a recording device, connected to the plurality of reproducing units, for receiving the data at the second transfer rate and recording the data on one of said master discs.

A method for recording data divided into a plurality of data blocks on master discs of a plurality of different types, comprising the steps of:

• transferring one of said data blocks at a first transfer rate to a memory device;
• storing the one data block at the first transfer rate in the memory device;
• outputting the stored one data block from the memory device at a second transfer rate, which is different from the first transfer rate;
• transferring another one of said data blocks to said memory device when said memory device finishes outputting said one data block which has been transferred to said memory device prior to said another data block;
• and
• recording the one data block outputted from said memory device onto a data track of one of the master discs at the second transfer rate such that a recording point where the one data block is recorded on the data track is moved in a radial direction of the one master disc by a moving distance per each unit time which is constant regardless of the type of the one master disc.
