Ramp member assembly including flying slider in recording disk drive
View Patent ↗A ramp member is supported on a flying slider in a load/unload mechanism of a recording medium drive. The flying slider receives a lift at its air bearing surface based on airflow generated along the moving recording medium. The flying slider flies above the recording medium. The flying height of the flying slider can be controlled with a higher accuracy in the same manner as a flying head slider utilized to read and write data from and into the recording medium. The slope of the ramp member on the flying slider can accordingly be kept at a predetermined level above the recording medium with a higher accuracy. Even if the extent of the slope is reduced, the load bar is allowed to reliably contact the slope. This leads to expansion of the data zone on the recording medium.
1. A recording medium drive comprising:
a recording medium;
a head slider opposing an air bearing surface to a surface of the recording medium;
a load bar fixed to the head slider;
a ramp member defining an inclined surface getting more remote from the surface of the recording medium along a path of movement of the load bar, said ramp member receiving the load bar at the inclined surface; and
a flying slider opposing an air bearing surface to the recording medium, said flying slider supporting the ramp member.
2. The recording medium drive according to claim 1 , further comprising:
a first support member supporting the flying slider;
a second support member fixed to an enclosure containing at least the recording medium and the head slider; and
a drive member interposed between the first and second support members, said drive member generating a relative displacement between the first and second support members.
3. The recording medium drive according to claim 2 , wherein said first support member is an elastic suspension.
4. The recording medium drive according to claim 3 , further comprising a lift mechanism contacting at least one of the elastic suspension and the flying slider, said lift mechanism designed to hold the flying slider at a position spaced from the surface of the recording medium.
5. A ramp member assembly for a recording medium drive, comprising:
a flying slider opposing an air bearing surface to a surface of the recording medium; and
a ramp member fixed to the flying slider, said ramp member defining an inclined surface getting more remote from the surface of the recording medium.
