Abstract

PURPOSE: To achieve the reduction in read errors in high density recording and novel recording type by recording the identification signals showing the recording density or recording type of the data part recorded on a medium over the entire track.
CONSTITUTION: Recording density identification signal ID bursts are recorded over the entire track of a recording medium, whereby not only the identificiation of the recording density or recording type of the data part is performed but also they are utilized in setting of the read amplification agains of the data parts. Thereby, the increase in the number of recording tracks, the increase in recording density and the decrease in read errors at novel recording types are performed and the effect of dust, flaws, etc. on the recording medium may be eliminted.
