    摘要： Data in CD signal format is recorded to a first portion of an optical disc and compressed digital data in CD-ROM format in double density is recorded to a second portion of the disc, with a blank gap between the first and second portions. Addresses of the first portion are represented in a notation of minute, second, and frame and addresses of the second portion are represented in binary notation. When assigning addresses it is determined whether the first portion is accessed, and when the first portion is accessed the generation of normal addresses is started. When the determined result represents that the first portion is not accessed, the gap length is calculated and the start address of the second session is generated based upon the end address of the first portion and the known gap length. It is then determined whether the second portion has ended. Unless the second portion ends, the generation of the second addresses is continued. When the second portion ends, the generation of addresses is stopped.

    摘要： Data in the same signal format as a conventional CD is recorded to a first part of a record medium and compressed digital data in CD-ROM format in double density is recorded to a second part of the record medium. Addresses of a first session including the first part are represented in the notation of minute, second, and frame, and addresses of a second session including the second part are represented in binary notation. When the record position is moved from the first session to the second session, an end address of the first session is converted into an address of the second session. The start address is then designated and 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.

    摘要： CD-ROM data is received to an interface 1. When a high reliability is required, a sector segmenting circuit 4 is selected by a switching circuit 3. The input data is sector segmented to the CD-ROM sector by the circuit 4. When a large recording capacity is requested, a CD-ROM decoder 5 is selected by the switching circuit 3. After the CD-ROM data was error corrected, user bytes in the data are sector segmented into 2-kbyte sector. The data converted into the CD-ROM sector or 2-kbyte sector is integrated to a block structure by the block segmenting circuit 7 and is, further, subjected to processes such as error correction coding and digital modulation by a recording processing circuit 8. A pattern of a sync that is added by the recording processing circuit 8 is made different in accordance with a sector construction. Recording data from the recording processing circuit 8 is recorded onto an optical disc 2 by an optical pickup 10.
