ABSTRACT:
A head arm to be mounted on the carriage of a disc memory drive has a two-stage lift mechanism. This reduces pitch of the head as it is lifted from and landed on the recording medium, reducing the danger that the head will penetrate the air film bearing and scuff the medium, a potential source of damage to either the head or medium.
