Abstract
According to an embodiment, a slider of a head is provided with a negative-pressure cavity 54 formed in a disk-facing surface, a leading step portion located on the upstream side of the negative-pressure cavity, a pair of side portions opposed to each other, a head mounting pad provided on the facing surface on an outflow side of the negative-pressure cavity with respect to an airflow and provided with a head portion, a positive-pressure generating pad which is arranged on the facing surface between a leading pad and the head mounting pad and configured to produce a positive pressure, and a pair of center skirts which are disposed on the outflow side of the positive-pressure generating pad and are shallower than the negative-pressure cavity.
Claims9
A head comprising:
- a slider comprising a surface configured to face a surface of a rotatable recording medium and to fly by an airflow between the surface of the recording medium and the surface as the recording medium rotates;
- and
- a head portion on the slider, configured to record information on the recording medium and to reproduce information from the recording medium,
- the surface of the slider comprising a first direction along the airflow and a second direction perpendicular to the first direction,
- the slider comprising:
- a negative-pressure cavity defined by a recess in the surface and configured to produce a negative pressure,
- a leading step portion on the surface and on an inflow side of the negative-pressure cavity with respect to the airflow,
- a pair of side portions on the surface, extending from the leading step portion toward an outflow end of the slider, and facing each other with a space between the pair in the second direction,
- a head mounting pad on the surface on an outflow side of the negative-pressure cavity with respect to the airflow with the head portion,
- a positive-pressure generating pad on the surface at a predetermined distance from the head mounting pad, on the inflow side with respect to the airflow, and configured to produce a positive pressure, and
- a pair of center skirts on the outflow side of the positive-pressure generating pad and being shallower than the negative-pressure cavity.
A head suspension assembly in a disk drive comprising a disk recording medium and a drive module configured to support and rotate the recording medium, the head suspension assembly comprising:
- a head comprising a slider comprising a surface configured to face a surface of a rotatable recording medium and to fly by an airflow between a surface of the recording medium and the surface as the recording medium rotates, and a head portion on the slider and configured to record information on the recording medium and to reproduce information from the recording medium;
- and
- a head suspension configured to support the head while moving with respect to the recording medium, wherein
- the surface of the slider comprises a first direction along the airflow and a second direction perpendicular to the first direction,
- the slider comprises:
- a negative-pressure cavity defined by a recess in the surface and configured to produce a negative pressure,
- a leading step portion on the surface and on an inflow side of the negative-pressure cavity with respect to the airflow,
- a pair of side portions on the surface, extending from the leading step portion toward an outflow end of the slider, and facing each other with a space between the pair in the second direction,
- a head mounting pad on the surface on an outflow side of the negative-pressure cavity with respect to the airflow with the head portion,
- a positive-pressure generating pad on the surface at a predetermined distance from the head mounting pad, on the inflow side with respect to the airflow, and configured to produce a positive pressure, and
- a pair of center skirts on the outflow side of the positive-pressure generating pad and being shallower than the negative-pressure cavity.
A disk drive comprising:
- a disk recording medium;
- a drive module configured to support and rotate the recording medium;
- a head comprising a slider comprising a surface configured to face a surface of a rotatable recording medium and to fly by an airflow between a surface of the recording medium and the surface as the recording medium rotates, and a head portion on the slider configured to record information on the recording medium and to reproduce information from the recording medium;
- and
- a head suspension configured to support the head while moving with respect to the recording medium, wherein
- the surface of the slider comprises a first direction along the airflow and a second direction perpendicular to the first direction,
- the slider comprises:
- a negative-pressure cavity defined by a recess in the surface and configured to produce a negative pressure,
- a leading step portion on the surface and on an inflow side of the negative-pressure cavity with respect to the airflow,
- a pair of side portions on the surface, extending from the leading step portion toward an outflow end of the slider, and facing each other with a space between the pair in the second direction,
- a head mounting pad on the surface on an outflow side of the negative-pressure cavity with respect to the airflow with the head portion,
- a positive-pressure generating pad on the surface at a predetermined distance from the head mounting pad, on the inflow side with respect to the airflow, and configured to produce a positive pressure, and
- a pair of center skirts on the outflow side of the positive-pressure generating pad and being shallower than the negative-pressure cavity.
