    摘要: A hard disk drive with a spindle motor that rotates a disk. When the disk drive is exposed to low temperatures a current can be provided to the spindle motor to heat the motor. For example, a DC current can be provided to the spindle motor. The current flowing through the spindle motor coil generates heat. The current can be provided for a predetermined time interval to sufficiently heat the spindle motor so that the fluid bearings of the motor can operate. The current is terminated and then an AC current is provided to the spindle motor to cause motor rotation.

    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.
