Abstract:
A rigid disk drive comprising:a baseplate;a rigid disk supported on said baseplate for rotation;an elongated actuator arm including a load beam, said actuator arm being pivotally supported about a center of rotation on said baseplate for rotation of one end of said load beam in a plane substantially parallel to a surface of said disk, said load beam including at its outermost end a lift tab;a slider body including a read/write recording element;means connected to said load beam and said slider body for supporting said slider body at a position intermediate said lift tab and said center of rotation; anda cam assembly supported on said baseplate adjacent to said lift tab and the edge of said disk; said cam assembly including a cam surface positioned in operative relationship with said lift tab, said lift tab contacting said cam surface and in cooperation with said cam surface providing a lifting force to said load beam, said cam surface including a first raised lobe, a second raised lobe and a detent disposed therebetween,wherein said actuator arm is movable in a first direction such that said lift tab is movable in said first direction from said detent along said first raised lobe during a positioning of said slider body over said disk, and said actuator arm is movable in a second direction, opposite said first direction, such that said lift tab is movable in said second direction from said detent along said second raised lobe and out of contact with said cam surface.
