An optical disk reading method comprising the steps of: processing an optical signal reflected from encoded pits on an optical disk until total number of data layers and pit configuration standard of the optical disk is identified; collating the processed optical signal with an optical disk standard data which is stored in a memory; and settling modulation of servomechanism means dependent upon the optical disk standard data which corresponds with the processed optical signal; (c) the servomechanism means including: a focusing lens servo to modulate position of a focusing lens; and a tracking servo to modulate movement of a pickup. view more
