Abstract: Disclosed are a method for reading data recorded on a burst cutting area (BCA) of an optical disc and an optical disc apparatus applying the method. The method comprises the steps of calculating a first driving voltage for driving a spindle motor corresponding to a speed required to read data from a BCA of the optical disc, in a predetermined data area of an optical disc by adjusting the driving voltage of the spindle motor, which rotates the optical disc. The BCA data is read by controlling the speed of the spindle motor according to the calculated first driving voltage.

Abstract: A time lapse recording apparatus for a DVCR and a method thereof are disclosed.

Abstract: A method for controlling the speed of a capstan motor in a video cassette recorder (VCR) includes modulating a capstan frequency generating (CFG) signal into a pulse signal. Time intervals corresponding to one of a rising edge to a next rising edge and a falling edge to a next falling edge of the pulse signal are calculated. The calculated time intervals are compared to a target time to obtain a difference therebetween. A rotation speed of the capstan motor is compensated based on the obtained difference to control the rotation speed of the capstan motor.

Abstract: A method for controlling tracking position during low-speed reproducing in a video cassette recorder (VCR) which provides noise suppression noise and increased image quality. In one aspect, in a VCR having a pair of main heads for reproducing video signals from a recording medium at a normal operating speed associated with said VCR, a method for controlling tracking position when reproducing at speeds lower than the normal speed comprises the steps of: detecting a period of an envelope waveform of a video signal which is reproduced by the pair of main heads; generating a pseudo head switching pulse (PHSP) signal in accordance with the detected period; and tracing a tracking position at a position where a voltage level of the envelope waveform is the largest within one period of the PHSP signal.

Abstract: A capstan phase control method during slow playback and the servo system of a VCR adopting the same, for phase-controlling a capstan motor so that a slow motion picture can be viewed without having noise during slow playback of the VCR. The capstan phase control method and the servo system employing the same, sets a sampling frequency of a reference control signal corresponding to desired slow playback on the basis of a head switching signal, judges whether a phase of the reference control signal having the set sampling frequency is identical with that of the control signal read via a head from the tape, and controls the phase of the capstan motor so that the phase of the read control signal is identical with that of the reference control signal on the basis of the judgement result. Accordingly, since the capstan motor can be phase-controlled and speed-controlled during slow playback, a tracking control can be performed so that noise does not appear on a screen.
