PRINCIPLES OF OPERATION
thermal-asperity detection
To detect thermal asperity, a DC comparator connected to the input of the booster amplifier is presented. The
device acknowledges V(RDX/RDY) > 460-mV MR-head read signal as thermal asperity and responds by:
a) Disabling RDX/RDY output buffers to avoid disturbing the next read channel
b) Reporting fault in read mode
Release timing is extended 100 ns from the end point of thermal-asperity detection.
The device behavior for thermal-asperity detection is shown in Figure 4.
