4.3 Magnetic Head and Disk
4.3.1 Magnetic head
To obtain a high recording density, advanced Winchester type CSS (Contact Start
and Stop) heads are used. While the disks are not rotating, the heads rest on
the disk surfaces in contact, but when rotation starts, the heads begin to
float over the disk surfaces. After the disks reach the specified rotational
speed, the heads maintain the flying height with the balanced force of each
load spring and the air-bearing between disk surfaces and the head sliders.
Therefore, to prevent wear caused
by
contact-start/stop, and to achieve minimum
but stable flying height, the head is loaded slightly and its slider rails are
tapered.

To increase the output voltage at high recording density, the core is made from
Mn-Zn instead of Ni-Zn which is the commonly used material.
