項記載の記録媒体演奏装置。[Claims for Utility Model Registration] (1) In a recording medium playing device that selects and plays a predetermined recording medium from a magazine containing a plurality of recording media, a nonvolatile memory for storing magazine identification data is provided in the magazine. At the same time, connecting means are provided on the magazine side and the main body side to connect the nonvolatile memory and the device main body so that data can be exchanged when the magazine is attached to the device main body, and furthermore, the magazine identification data is stored in the nonvolatile memory. 1. A recording medium performance device, characterized in that the device main body is provided with a control means for writing predetermined magazine identification data into the nonvolatile memory if the data has not been written. (2) The control means includes a monitoring means for monitoring the current date and/or time, a magazine identification data creation means for creating data corresponding to the date and/or time at the time of mounting the magazine as magazine identification data, and a magazine identification data creation means for creating the magazine identification data. Utility model registration claim 1 characterized by having a means for sending data to the magazine side and writing it into a non-volatile memory
Recording medium performance device as described in Section 1.
