摘要:
Disclosed is an apparatus and method for correcting for track misregistration when a slider or head assembly contains a separate read element (40) and write element (42). Basically, the offset is determined at a first position and at a second position of the actuator arm (48) assembly. From these offsets a constant and a multiplier are determined for determining an offset as a function of the cylinder location. Also disclosed is a method and apparatus for minimizing distance traveled to prevent misregistration when repositioning between the read element and a write element. The read element is intentionally offset from the write element at an angle so as to minimize the distance traveled across the disk.
摘要:
During manufacture of a flexible disk drive (102), the magnetic head (101) 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 (166). The head signal is used to produce 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 secured to the head carriage (168) of the disk drive by irradiating radiation curable adhesive therebetween.
