Abstract
A low cost, reliable and high density magnetic disk device of a ramp loading type, in which a ramp or a dimple or dimples are free from wear even if loading and unloading are repeated. A plurality of dimples are arranged or running tracks are inclined so that the running tracks (ramp), on which a portion (a dimple or dimples) of a magnetic head supporting mechanism runs, includes different tracks at the time of loading and unloading. Alternatively, the magnetic head supporting mechanism has different portions engaging with the ramp at the time of loading and unloading.
Claims6
A magnetic disk device comprising a magnetic head supporting mechanism composed of a magnetic head for recording information on and reproducing information from a magnetic disk, a suspension for supporting a slider provided with said magnetic head, and an arm for supporting said suspension;
- a drive mechanism for moving said magnetic head supporting mechanism to a predetermined position;
- said magnetic disk for recording thereon information, and a stationary ramp section having running tracks which enable a tip end of said magnetic head supporting mechanism to be loaded onto said magnetic disk or unloaded therefrom, and wherein said magnetic head supporting mechanism runs on different running tracks on said stationary ramp section at the time of loading and unloading.
