Tilt compensation method and apparatus

摘要

Provided is a tilt compensation method and apparatus that effectively compensates for a tilt of an information storage medium. The tilt compensation method includes calculating a tilt value at more than one local point of the information storage medium using a focus-on-drive (FOD) sensitivity function and a tilt sensitivity function of a pickup of a recording and/or reproducing apparatus which records data onto and/or reproduces data from the information storage medium, obtaining a skew component of the pickup, obtaining an abnormal component caused by a sensitivity difference of the pickup with respect to the information storage medium; and compensating for the calculated tilt value using the obtained skew and abnormal components.
