  • Servo information recording method, magnetic recording media, and magnetic disk apparatus
    Patent number: 7365933
    Abstract: Embodiments of the invention provide optimum servo patterns for perpendicular magnetic recording method. In one embodiment, a burst field of servo patterns is composed of burst-signal parts in each of which a constant frequency occurs successively and zero-signal parts each of which has been demagnetized to a state of zero-magnetization, and the total magnetization of the burst field is made approximately 0. The zero signal portions are formed by shutting off a write current at a time during an operation to record servo patterns on a disk initialized to a state of zero-magnetization. The total magnetization of all servo patterns is made approximately 0 by encoding an address mark field and a track code field of servo patterns by a phase shift method.

  • Load/unload mechanism for magnetic disk drive
    Patent number: 7365930
    Abstract: Formation of wear powder caused by wear of a ramp which is attributable to mutual contact of a lift tab and the ramp is to be reduced in loading and unloading operations. In one embodiment, a spindle motor is turned on by application of power, then the temperature of a ramp is measured and it is determined whether the temperature of the ramp has reached a preset temperature (about 25° C.) or not. If the answer is negative, a heater is energized to heat the ramp for raising the temperature of the ramp. When it is detected that the temperature of the ramp has reached the preset temperature, the heating of the ramp is stopped and the execution of loading and unloading operations is permitted, then an ordinary processing is started.
