Abstract

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.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 81 words
An optical disc player for reproducing a musical program recorded on an optical disc having a TOC area storing the start and end times of each musical program and additional information, wherein a lapse time is displayed on a display unit in a usual case during the performance of a musical program, and when a title key is depressed, the additional information such as the title of a musical program is displayed on the display unit for a predetermined time period.
Claim 2
Dependent Claim 141 words
A photomagnetic disc recording/reproducing apparatus for reproducing a musical program recorded on a rewritable photomagnetic disc of the type that an absolute time is FM-modulated and recorded on a wobble of a groove in a program area of a record/reproduction area for each musical program and the start and end times of each recorded musical program are recorded in a user TOC area, wherein record information of an optional musical program stored in said user TOC area and including said start time is erased by depressing an erase key during the performance of said optional musical program so that user TOC information of said optional musical program stored in a RAM of the recording/reproducing apparatus is erased, and that the contents of said RAM are recorded in said user TOC before said photomagnetic disc is ejected out from the recording/reproducing apparatus.
Claim 3
Dependent Claim 66 words
A photomagnetic disc recording/reproducing apparatus according to claim 2, wherein two consecutive musical programs are combined as having a single musical program number by depressing a cancel key during the performance of the later musical program of said two consecutive musical programs, and an optional musical program is divided into two musical programs by depressing an insert key during the performance of said optional musical program.
