Abstract
The Invention Provides a Positioning System for a Linear Data Storage Medium, Such as magnetic tape or other data storage medium in which data is stored on parallel data tracks that extend along a length of the medium. The invention makes use of multiple actuators to control the positioning of sliders carrying read and write elements, e.g., separate sliders carrying the read and write elements, relative to the data storage medium with multiple degrees of freedom. The multiple degrees of freedom may include two or more of a vertical position, a horizontal position, a transverse position, an azimuth position, a zenith position, and a yaw position. In this manner, the invention can improve head-to-track alignment of read heads and write heads with linear data storage systems having very small track pitches, such as track pitches approximately 1 micron and especially less than 1 micron.
