Compact Head Stack

A compact height/glide tester head stack design meets the requirements of close disk spacing and provides that the trailing edge of the slider is leading during access from the outer diameter to the inner diameter of a magnetic disk.

The glide head assembly is shown in Fig. 1, with the glide heads 1,2 at the outer position. The heads 1,2 are offset from each other to allow two heads to fit in the gap between disks. The top flying head 1 has a zero degree skew angle and the bottom flying head 2 has a 4 degree skew angle. The heads are moved to the inner position of Fig. 2 along a radial line 3. The trailing edge 4,5 of each head is always testing the new area of the disk before the leading edge of the heads. At the inner position (Fig. 2) the top head 1 has a 5 degree skew angle and the bottom head 2 has a zero degree skew angle.
