SOLT NOISE ELIMINATION METHOD IN CASE OF TILT ADJUSTMENT USING TRACKING ERROR AND ADJUSTMENT ERROR IMPROVEMENT METHOD

摘要

The present invention relates to a tilt adjustment Salt noise removal method using a TE, TE measured data obtaining a pure TE data by the effects of the tilt adjustment only to sequentially perform by performing a median filter to remove noise, the salt (salt noise), and the averaged and smoothed waveform using; And during the same time when the measurement data obtained for one of the TE in any tilt adjustment value by measuring the number of TE shorter cycle data after it performs a median filtering step of using the result as the representative value for the tilt adjustment value includes. And the same method can significantly improve the adjustment and the adjustment deviation o problem occurs when using who size of the TE signal in the tilt adjustment of the existing blank disc. These improvements can lead to performance improvement of the recording quality on the stable operation of the RF servo side by increasing the accuracy of the tilt adjustment of the blank disc.
