Filed: 2000-11-21
Abstract: PURPOSE: A method and a system for controlling a tilt are provided to detect a locus of an FE(Focus Error) signal at a point where an RF(Radio Frequency) signal becomes peak or of an FE signal having a minimum jitter, and to deduct DC(Direct Current) and AC(Alternating Current) components. CONSTITUTION: A system is run and initialized(51,52). An optical pickup unit performs focusing to discriminate whether a disk exists. If exists, focus servo is performed and initialization values of each component of a system are changed and set according to the discriminated disk. And if a disk does not exist, disk insertion is waited(53,54,55). When performing focus servo, initialization and the focus are turned 'on'(56,57). Tracking offset and balance are performed for stable tracking servo(58,59). A tilt controller is wobbled by a predetermined reference level, and a locus of an FE signal is obtained at a point where an RF envelope signal becomes peak as a tilt error. Offset for the tilt error is detected to deduct a driving amount for controlling a tilt. A factor of controlling a tilt is decided by regarding a normalized value of the tilt error value as a tilt control reference value(60). A spindle motor is operated, to detect an FE DC variation and an FE AC variation(61,62). When seeking is performed, the tilt and tracking servo are turned off and a sled is moved to a desired position, then the tilt and tracking servo are turned on(64,65,66).

The shift register comprises a number of flip flops and outputs a control signal(DCON) to control a delay time of the delay line to the delay line. And the phase detector also outputs an up control signal(UP) and a down control signal(DOWN). A charge pump(50) outputs an analog control signal(VCON) to control the delay time of the delay line in response to the up or down control signal. The delay line performs a coarse locking in response to DCON, and performs a fine locking in response to VCON. An output buffer(70) outputs data(OUT_DAT) stored in a memory cell array by being synchronized to the internal clock.
