Paper Abstract

Plan: 1) Actual Positioning Method 2) Sample Format Versus "Continuous" Format 3) Sample Access Methods Actual Positioning Method The small track pitch (equal to or less than 1.7 um) of digital optical disk devices makes a conventional mechanical access to a track very difficult to achieve. In fact, the eccentricity of the central hole (about 40 um) does not allow an absolute mechanical access to find a track.
