摘要： A method of detecting a bad servo track of an HDD includes measuring servo AGC of each of servo sectors of a servo track requiring determination of badness, calculating statistic data with respect to the measured servo AGC of each servo sector, and determining whether the servo track is bad based on the calculated statistic data. Since the badness of a servo track is determined based on the statistic data of the servo AGC, a bad servo track generated due to a change in the overall magnitude of a servo signal is easily detected so that reliability in the detection of a detective servo track can be improved.

摘要： In a video stabilizing circuit for a display apparatus, the clamp levels of R, G and B chromatic signals are controlled by feeding back the output currents of respective R, G and B terminals so that real time responses can be made, as against the fluctuations of video output load, thereby obtaining high brightness displays. The circuit according to the present invention is characterized in that output currents of R, G and B terminals are fed back from video output sections to clamp level control sections. The potential of a cut-off control terminal of the video pre-amplifier is then varied in such a manner that, if the beam current sensed by the clamp level control section is large, the bias voltage of the chromatic signals is made small. If the beam current sensed by the clamp level control section is small, the bias voltage of the chromatic signals is made large. Therefore, during a high brightness display, fluctuations in the brightness of the high beams and low beams is reduced and display is improved.

The reproducing circuit stably separates the horizontal and vertical sync signals from the luminance of a composite video signal, and the separated sync signals enable the composite video signal and the VGA video signal to be discriminated.
