Abstract
An apparatus and a method for reducing a lead-in time of a disc, on which data is always recorded, and detecting exactly a tilt of the disc. The apparatus includes a pickup, and a system controller. Even if the disc is a blank disc which is devoid of user data, control data is recorded on the disc. The pickup can record data on the disc or reproduce data from the disc. If a seek command is received, the system controller detects the tilt of the disc once in each of a plurality of zones while the pickup is moving.
