Abstract

PURPOSE:To record or reproduce information different in form on or from the same recording medium under a mixed condition of the information by recording two forms of information on the same recording medium under a mixed condition after respectively adding discriminating information to the information. CONSTITUTION:Document and picture information and sound information are respectively inputted from a scanner circuit 1 and sound inputting circuit 3 and selected at a gate circuits 5 after passing through an information compressing circuit 2 and sound encoding circuit 4. Upon receiving discriminating information from a discriminating information circuit 6, a modulator circuit 7 makes EFM modulation on the document and picture information and sound information from the gate circuit 5 and, at the same time, records each information on an optical disk 8 after adding the discriminating information to each information. Document and picture information and sound information read out by detecting the header information from the disk 8 are supplied to a discriminating information recognizing circuit 10 where the discriminating information is extraced through a demodulator circuit 9 and selected at a gate circuit 11. After the selection, each information is sent to a display 14 where the document and picture information is displayed and a sound outputting circuit 15 where the sound information is outputted through an information extending circuit 12 and sound decoding circuit 13.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Industrial Applicability The present invention relates to a companion information recording method for recording different types of information on the same recording medium.

(b) i Prior Art In general, information recorded on information recording media such as optical disks and magnetic disks includes f-voice information, color video information, tFi document and image information, and the like.

Currently, document information file devices that record document and image information on optical disks are attracting attention because of their large recording capacity. This type of apparatus is configured to form a dot pattern by optically reading a W original and record it on an optical disk.

On the other hand, there is a method of recording and reproducing audio information, color video information, etc. using an optical disk.

By the way, if these different formats of information could be recorded and reproduced on the same optical disk, it would be possible to use these information in conjunction with each other, which would be very convenient.

Conventionally, when recording such different types of information on the same recording medium, the information is divided into the outer circumferential part and the inner part of the recording medium, as shown in Japanese Utility Model Publication No. 40-32203. .
