Abstract

A problem is disclosed in development phase for new microdrive which includes 1 head that the actuator escaped to disk. The main factor of this problem is the much power to retract actuator. However, the power was needed to retract actuator in microdrive which includes 2 head. This is the mechanism for this problem.

MahRamp [Ramp with trap]

A problem is disclosed in development phase for new microdrive
which includes 1 head that the actuator escaped to disk. The
main factor of this problem is the much power to retract
actuator. However, the power was needed to retract actuator in
microdrive which includes 2 head. This is the mechanism for this
problem.

To solve this problem, the shape of ramp slope is changed as
following figure.

Figure

MahRamp has addtitional dent at flat zone. The parameters of
this dent are determined by the shape of merge lip of HGA.

The escape to disk had occured at half of the tested drives which
included current ramp, but no escape to disk had occured at the
tested drives which included Mahramp.
