Abstract

PURPOSE: To achieve the improvement in slicing accuracy by defining the working pitch of grooves for specifying track width and slicing pitch at specified integer values.
CONSTITUTION: If the working pitch PD of grooves for defining track width and slicing pitch PS are so selected in integer number μm that 100 times the decimal point of the error between the theoretical pitch PDCosθ and the pitch PS corresponding to azimuth angle θ becomes less than 1, then high accuracy sliding in which such thing as a slicer exceeds the groove and rides on the gap part owing to the cumulative error of 100 pieces of azimuth heads by sliding of a working error limit 1μm is obviated may be performed.
