Abstract

Disclosed is an actuator lock apparatus by using a local part of VCM magnet in L/UL Hard Disk Drive(HDD). Fig.1 shows an example of the L/UL (Load/Unload) Hard Disk Drive mechanism and Fig.2 shows the detail of Actuator(a) and VCM magnet(b). The actuator(1) stays at the Parking Area(3) on the Ramp(2) while power is off. The clockwize motion of Actuator(1) is restricted by Actuator Lock(7) which must have an additional magnet in itself because of L/UL requirement by Ramp Slope(4) and Latch(8).
