Abstract
The present invention provides an integrally formed ramp that is used for evacuating the suspension arm of a data storage device. The ramp has sliding portions, each having guiding zones and a landing zone. The boundary between the guiding zones and the landing zone is formed parallel to a reference line, so even if the landing portion had a recessed shape, the sliding portion could be molded with a casting mold by pulling out the casting mold in the direction of the reference line. The necessary portion of a support portion which is formed with the same casting mold as the sliding portions is formed so as not to disturb the pulling-out of the casting mold in the direction of the reference line. The integrally molded ramp is high in fabrication accuracy and excellent in defining an accurate loading/unloading position of the suspension arm.
