Patent number: 6026676Abstract: A glide head with mounted PZT sensor is used to obtain a glide avalanche curve. The glide head is subsequently gradually decreased until the signal is extremely high. First, at least one resonance frequency of the glide head is determined. The frequency component of the PZT glide signal to each specific irregular peak is analyzed by using the speed of the glide head divided by the bump spacing, multiplied by a factor, m, where m is an integer number. The next step of the present invention is to determine a glide avalanche break point of the recording medium. Then, the glide avalanche point is determined in the region which is between the irregular peaks and the extremely high signal.Type: GrantFiled: July 2, 1997Date of Patent: February 22, 2000Assignee: Trace Storage Technology Corp.Inventors: Hung-Wei Chen, Teng-Chien Yu, Ming-Hung Su, Yi-An Chen, Philip Yong
