Abstract:
A head loading apparatus for a disk drive device that reads data from and writes data to a magnetic medium, said head loading apparatus comprising:an actuator movably disposed within said disk drive device;a read-write head in mechanical communication with said actuator, said actuator moving said head in response to an electrical signal, said read-write head detecting the completion of the loading by detecting a signal from said magnetic medium;a head load ramp for maintaining said read-write head in a parked position off of said medium;means in electrical communication with said actuator for moving said head from said parked position to said medium by applying said electrical signal;said electrical signal varying such that said head moves off of said load ramp toward said medium at a varying acceleration without measuring the velocity of the head movement;wherein said electrical signal comprises at least two on times and at least two off times, wherein said off times are selected such that said movement of said head from said parked position toward said medium substantially stops before the application of the next on time of the electrical signal.
