Title: Device and method for correcting tilt
Inventor: KATO MASAHIRO
IPC: G11B7/095
Filed: 2002-08-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide a device for correcting radial tilt by using a reproducing signal form an optical disk without disposing any dedicated tilt sensors.  <P>SOLUTION: In one disk, there is a difference equivalent to a predetermined offset amount between a radial tilt correction amount when RF signal amplitude is maximum, and a radial tilt correction amount when LPP signal amplitude is maximum, and this does not vary from position to position on the disk. Thus, in tilt correction, the radial tilt correction amount when the RF signal amplitude is maximum is set as an optimal correction amount in a recorded disk and, in an unrecorded disk, an optimal correction amount is decided by considering the offset amount plus the radial tilt correction amount when the LPP signal amplitude is maximum. Thus, radial tilt is accurately corrected not only in the recorded disk but also the unrecorded disk.  <P>COPYRIGHT: (C)2004,JPO
