Abstract:
A Pre-Contact Signal Detector (PCSD) used to predict contact between read-write head and disk surface. A preamplifier may include the PCSD. A main flex circuit may include the preamplifier. A head stack assembly may include the main flex circuit. An embedded circuit may use a pre-contact alert circuit, which may also be included in the PCSD and/or the preamplifier, also the main flex circuit, the head stack assembly. A hard disk drive may include the head stack assembly communicating with the embedded circuit. Manufacturing methods for these and their products of the manufacturing processes, including the program system.
