Abstract

An optical disc, and a disc recorder and a disc reproducer therefor, wherein in a lead-in region of the disc table of contents data indicating the record position on the disc of main data, e.g. musical numbers or the like, are recorded as subcodes and display data of, e.g. the titles of the musical numbers, the performers, etc., are also recorded as main data and wherein in a data region on the disc are recorded play data for the musical numbers as well as display data of the titles, performers, etc. of the musical numbers.

Claims

1. An information storage disc reproducing apparatus for reproducing an information storage disc having a lead-in region in which display data of a record contents of a data region on the information storage disc are recorded as main data and table-of-contents data indicating a record position of said data region are sub-coded and recorded, comprising:

reproducing means for reproducing said record contents from said data region and display data recorded in said lead-in region as main data,

a memory for storing said display data reproduced from said lead-in region,

display means for visually displaying said display data obtained by said reproducing means and stored in said memory, and

display control means for performing a display control based on said display data stored in said memory.

2. The information storage disc reproducing apparatus according to claim 1 wherein said display control means visually displays display data of a song from among said record contents during a reproduction of said song and displays display data of the information storage disc in its entirety during a cessation mode.

3. An information storage disc recording/reproducing apparatus comprising:

recording means for recording as main data in a lead-in region of an information storage disc, display data of a record contents of a data region of said information storage disc and for recording as sub-codes in said lead-in region, table-of-contents data indicating recording positions of said data region,

reproducing means for reproducing said display data from said lead-in region,

a memory for storing display data reproduced from said lead-in region,

display means for visually displaying said display data reproduced by said reproducing means and stored in said memory, and

display control means for performing a display control based on said display data stored in said memory.

4. The information storage disc recording/reproducing apparatus according to claim 3 wherein said information storage disc has a reproduce-only region and a recordable region, and a lead-in region in which said display data are recorded as main data is provided in each of said regions.

5. The information storage disc recording/reproducing apparatus according to claim 3 wherein said display control means perform a display control of displaying data of a song being reproduced during a reproducing operation and displaying data of said information storage disc in its entirety during a cessation mode.

6.
