Abstract:
An information data recording method for recording an M-value information data at recording points interspersed on recording tracks of a recording disc, wherein (m.times.n) recording points exist on n adjacent recording tracks (n is a natural number equal to or larger than two) including a target recording point and exist on m adjacent disc radial lines (m is a natural number equal to or larger than two) including said target recording point, said method comprising the steps of:subtracting each of recording data recorded at each of (m.times.n-1) recording points other than said target recording point, within said (m.times.n) recording points, from said information data to produce a subtraction result;performing a residual operation on said subtraction result with the value of M to derive a residue value; andrecording said residue value as recording data to be recorded at said target recording point.
