  • Patent number: 8154819
    Abstract: The flying heights of magnetic heads of a disk drive are set using an FOD (flying on demand) method in a bank mode. A first signal for adjusting the flying height of a magnetic head is issued to each magnetic head and the value of the first signal is scaled by scale values set for the magnetic heads, respectively, with one of the scale values differing from the others. The value of the first signal is changed until the magnetic head associated with the scale value different from the others touches down. A flying height for the magnetic head which touched down is determined based on the value of the first signal at the time of touch-down. The process is repeated, however with a different bank of scale values each time and set in such a way as to cause the sequential touch-down of the remaining magnetic heads, and determinations of flying heights for the magnetic heads.

  • Patent number: 7767565
    Abstract: A method of fabricating a semiconductor device includes forming a first vertical pillar over a semiconductor substrate. A spacer is formed over a sidewall of the first vertical pillar. A portion of the semiconductor substrate exposed between the first vertical pillars is etched to form a recess that exposes a second vertical pillar extending below from the first vertical pillar. A sacrificial film is formed over the semiconductor substrate including the recess and a sidewall of the first vertical pillar to fill the recess, the second vertical pillar and the first vertical pillar. A supporting layer is deposited over the sacrificial film and the first vertical pillar. The supporting layer is patterned to form a supporting pattern connecting the first vertical pillar with each other. The sacrificial film is removed to expose the second vertical pillar. A surrounding gate is formed over a sidewall of the second vertical pillar.
