Zusammenfassung:PROBLEM TO BE SOLVED: To solve the problem that since a variation in quality due to differences of manufacturing times/manufacturing places is caused in identical recording media, it is necessary to perform recording into recording media by changing over parameters for recording (write power and a write strategy) for each of manufacturer's serial numbers which show the differences of the manufacturing times/manufacturing places. SOLUTION: This recording quality assurance system is constituted so that before performing recording, a manufacturer's serial number is transmitted to server computers of the maker of a recording and reproducing device, and the maker of a recording medium and parameter information for recording which is optimum and corresponds to the lot number is downloaded from the server computer of the maker of the recording and reproducing device and also the parameter information is written in a nonvolatile memory of a recording and reproducing device and the recording is performed using the parameter information which is optimum and corresponds to the lot number.
