Abstract
We propose a basic design guide to design a very low spacing slider for small magnetic disk drives. The design features; (1) A multipad or side-step slider to avoid a sudden decrease in flying height due to the yaw angle of the swing actuator. (2) The slider must be as small as possible to be stable because the very low flying height makes the slider tend to vibrate unstably. (3) High spacing mode must be avoided to stabilize the negative-pressure slider used in constant density recording (CDR) suitable for high-density magnetic media.
