Abstract
A data storage system includes one or more individual ramp faces for each to slidably receive the free end of a tab member connected to one of one or more transducer heads mounted on a head actuator assembly. Each head is disposed to fly in data transfer relationship adjacent to a respective rotating disk surface. Each ramp face is disposed on one of one or more individually adjustable ramp members connected to ramp mounting means. The ramp mounting means, the actuator assembly, heads and the disks are mounted on a rigid base in cooperating relationship. Head actuator assembly positioning means for moving the heads along the disk surfaces positions each head with respect to the corresponding disk surface so the respective tab is in sliding contact with the associated ramp face when the head is to be lifted from the related disk surface. The respective ramp face is arranged so that the corresponding head will be lifted safely from the disk surface to at least a predetermined parking distance as the free tab end slides outward along the respective ramp face. Multiple individual ramp face adjusting means is provided to enable multi-disk/head systems to have minimal wasted disk surface and minimum disk to disk spacing for given actuator/head geometry by adjusting the position of each ramp face with respect to each related head and tab when the actuator positioning means positions the heads at a maximum outer data transfer radius or when the positioning means positions the heads at a minimum disk to head safe displacement spacing.
