摘要： This application discloses a hard disk drive and operates it based upon using a first and third harmonic amplitude generated from reading a repeated pattern of bits written to a track on a disk surface. Both amplitudes are used to create a first data set and the third harmonic amplitude is used as a single tone to create a second data set. A conversion factor between these two is determine, which may be used to convert the first data set under other conditions into a temperature insensitive table of the electrical stimulus of a vertical micro-actuator and the flying height change of the slider. The hard disk drive may be calibrated during manufacture and/or in the field.
