Abstract
In an information recording, a first data processor divides input data into a plurality of frames so as to arrange the plurality of frames for each unit block. The unit block is a unit of error-correction with respect to the input data and the frames include first identification information, respectively. A second data processor inserts a linking block on a boundary portion between unit blocks in the record data. The unit blocks are adjacent to each other. The linking block includes a second identification information and the second identification information is different from each of the first identification information. A controller controls to record the unit block and the linking block on the information recording medium.
Claims8
An information recording medium, comprising:
- unit block areas in which unit blocks are divided into a plurality of frames to which sync codes are added respectively, and are recorded, each of the unit blocks being a unit of error correction with respect to record data;
- and
- linking areas, each of which is inserted between adjacent unit blocks, in which linking information is recorded, the linking information is divided into a plurality of frames to which sync codes are added respectively,
- wherein the sync codes in the linking areas have sync patterns different from those of the sync codes in the unit block areas.
An information reproducing apparatus for reproducing record data which is recorded on the information recording medium,
- the information recording medium comprising:
- unit block areas in which unit blocks are divided into a plurality of frames to which sync codes are added respectively, and are recorded, each of the unit blocks being a unit of error correction with respect to record data;
- and
- linking areas, each of which is inserted between adjacent unit blocks, in which linking information is recorded, the linking information is divided into a plurality of frames to which sync codes are added respectively,
- wherein the sync codes in the linking areas have sync patterns different from those of the sync codes in the unit block areas and
- the information reproducing apparatus comprising:
- a sync code detecting device which detects said sync codes added to said linking information from the reproduced record data;
- and
- a reproduction controlling device which determines a location of said linking area based on said detected sync codes.
An information reproducing method of reproducing record data which is recorded on the information recording mediums,
- the information recording medium comprising:
- unit block areas in which unit blocks are divided into a plurality of frames to which sync codes are added respectively, and are recorded, each of the unit blocks being a unit of error correction with respect to record data;
- and
- linking areas, each of which is inserted between adjacent unit blocks, in which linking information is recorded, the linking information is divided into a plurality of frames to which sync codes are added respectively,
- wherein the sync codes in the linking areas have sync patterns different from those of the sync codes in the unit block areas and
- the information reproducing method comprising the processes of:
- detecting said sync codes added to said linking information from the reproduced record data;
- and
- determining a location of said linking area based on said detected sync codes.
