Summary: | A method and system are provided for minimizing or optimising radial to vertical crosstalk (RVC) in an error signal in an optical record carrier reader is record carrier losed. Focus error offset values are applied to the reader. The radial to vertical crosstalk is determined after each focus error offset value is applied. The focus error offset value which minimizes or optimises the radial to vertical crosstalk is selected for use by the reader. |
