Disk drive ramp structure having integrated discrete rigid support elements for data storage device
A ramp structure for a data storage device has a load/unload ramp and a disk attached to a spindle. The ramp structure has a first rigid support structure 52, a second rigid support structure 76 separated from the first rigid support structure, a bridge 78 that connects the first rigid support structure to the second rigid support structure, and ramp units 50 attached to the first rigid support structure. The rigid support structure has a thermal expansion coefficient selected so that the ramp-disk spacing is constant during changes in temperature. By placing the parts of the first rigid support structure 52 and the second rigid support structure sleeve 76 in an injection molding die and carrying out an insert molding, the ramp unit 50 has an accurate and stable size.
