That is,, divide into the ADIPWord (Address In Pre-Groove Word) of 4 sector record sizes, then each self-routing (ADIP Word# 1 ~ #4) error correcting code with 16 sector record sizes.At this moment, an ADIP Word equals 52 ADIP units, and each ADIP Word sintering forms the synchronizing signal (ADIP Sync) that writes down 1 the ADIP unit that is made of 93 shakes.
In addition, to indicate its 51 later ADIP units are physical address data to above-mentioned synchronizing signal.At this moment, above-mentioned synchronizing signal has any one encoded radio of prior setting.
Therefore, the BPSK of the above-mentioned DVD-RW of being applicable to shake addressing mode needn't resemble the CAPA mode also will be at other Pre-Pit recording address information.So, have the advantage that the data recording capacity that prevents to write down real data reduces.
But, as above-mentioned BPSK shake addressing mode is the synchronizing signal record that forms the shake shape with 4 sector units, so though can carry out the random access of error correcting code unit or data rewrite (Over Write) etc., existing can't be by the problem of each sector addressing.

That is, have the ECC piece of 16 sector record sizes, divide into each self-routing of ADIPWord (Address In Pre-Groove Word) (ADIP Word# 1 ~ #4) of 4 sector record sizes.At this moment, the 52 ADIP units that constitute an ADIP Word are dividing into 13 ADIP units corresponding and a sector.
In addition, above-mentioned corresponding to forming the synchronizing signal (SY0 that constitutes by 93 shakes in each first ADIP unit in the 13 ADIP units of a sector, the record of SY1 ~ SY15), 12 later ADIP units of above-mentioned synchronizing signal indication all are physical address data (Physical Address Data), and above-mentioned synchronizing signal will have mutual separately different types of encoded radio.
Therefore, have each sintering, sector in the 16 sector records size ECC piece, the synchronizing signal that is made of 93 shakes will form the shake shape record with intrinsic encoded radio, and distinguishing its later 12ADIP unit of indication with this all is physical address data.
