ABSTRACT:
During manufacture of a flexible disk drive, the drive's head is located in its penetration, radial, azimuth, tangential, roll and pitch attitudes by reading a test disk, as the head is held by a robotic head holder/manipulator. The head's signal produces closed-loop control of a serially-stacked array of rotary and linear motors which position the holder/manipulator. After the head is properly adjusted, it is clamped to the disk drive's head carriage.
