When contact frequency exceeds the threshold value, the contact detecting circuit notifies a controller of an error. Thereby, reduction of performance by erroneous detection of contact can be avoided. The AE uses the servo/gate synchronizing signal also in the other function. Thereby, the number of transmission lines between the AE and the HDC can be reduced.  <P>COPYRIGHT: (C)2011,JPO&INPIT
