Abstract
A simple equation which gives the crosstalk-free condition for land/groove recording of optical discs is deduced. Making use of this equation, the groove depth which minimizes the crosstalk from adjacent tracks is easily calculated. For simultaneous suppression of both the on-groove crosstalk and the on-land crosstalk, two practical approaches are proposed for the phase modulation discs. This equation is also of use in the signal estimation of optical discs.
