ABSTRACT:
Large characters and numerals of a lapse time, a musical program title, or the like of a musical program under the performance recorded on a photomagnetic disc can be displayed, and an inadvertent erase of a musical program can be prevented. The TNO and lapse time of each musical program during the performance are displayed on a display unit as shown in FIG. 3 at (f). Under this condition, when a title key is depressed, the title for the TNO is displayed for a predetermined time period on the display unit as shown in FIG. 3 at (g). After the predetermined time period, the lapse time for the TNO is displayed as shown in FIG. 3 at (h). When an erase key is depressed during the performance of a musical program, a controller erases the disc management information and additional information for the TNO from a RAM storing U-TOC information, and renumbers other TNOs to update the contents of RAM. Upon depression of a tray open key of a key matrix, the controller instructs an MD record/reproduction unit to stop the reproduction and copies the management information and additional information for the TNO stored in RAM to another RAM and records the copied information to a U-TOC area of a mini disc. Thereafter, the MD record/reproduction unit operates to eject out the disc cartridge.
