Abstract: AN ABSOLUTE TIME AREA IS EXPANDED BY USING AN AREA OF RELATIVELY LOW IMPORTANCE SUCH AS ZERO-DATA AREA AND /OR RELATIVE TIME AREA OR THE LIKE IN A Q CHANNEL IN A SUB-CODE IN A RECORDING FORMAT OF A CD . THUS, AN ABSOLUTE TIME EXPRESSION WHICH CAN COP WITH A DISC HAVING A LARGE CAPACITY OR THE LIKE CAN BE PERFORMED . AN ABSOLUTE TIME EXPRESSION IS PERFORMED IN A MANNER SUCH THAT A DIGIT OF " 100 MINUTES " IS BCD EXPRESSED BY USING LOWER 4 BITS IN THE 8-BIT ZERO-DATA AREA ZERO.THUS, THE ABSOLUTE TIME OF UP TO 999MIN 59SEC 74FRAME CAN BE EXPRESSED . A DIGIT OF "HOUR" IS ALSO EXPRESSED BY USING LOWER 4 BITS IN THE ZERO-DATA AREA . FOR EXAMPLE , IDENTIFICATION INFORMATION SHOWING THAT A DISC IS A HIGH DENSITY OPTICAL DISC (1) OF A LARGE CAPACITY IS EXPRESSED BY USING UPPER 4 BITS IN THE ZERO-DATA AREA ZERO.FIG.10

Abstract: Data in the same signal format as conventional CD is recorded to a first part PA1. Compressed digital data in CD-ROM format in double density is recorded to a second part PA2. Addresses of a first session including the first part are represented in the notation of minute, second, and frame. Addresses of a second session including the second part are represented in binary notation. When the record position moved from first session to the second session, the end address of the first session is converted into an address of the second session (at step S3). At step S4, designating the start address as address B, second addresses (for example, addresses represented in binary notation) are generated. When there is a non-record portion between the two sessions, an address value corresponding to the non-record portion is added to the start address. The resultant address is used as the new start address.

Abstract: An absolute time area is expanded by using an area of relatively low importance such as zero-data area and/or relative time area or the like in a Q channel in a sub-code in a recording format of a CD. Thus, an absolute time expression which can cope with a disc having a large capacity or the like can be performed. An absolute time expression is performed in a manner such that a digit of "100 minutes" is BCD expressed by using lower 4 bits in the 8-bit zero-data area ZERO. Thus, the absolute time of up to 999min59sec74frame can be expressed. A digit of "hour" is also expressed by using lower 4 bits in the zero-data area. For example, identification information showing that a disc is a high density optical disc of a large capacity is expressed by using upper 4 bits in the zero-data area ZERO.
