Abstract:
1. A method for high-speed massive magnetic imaging on a spin-stand comprising the steps of: (a) establishing a hard disk mounted on a spindle of a spin-stand; (b) establishing position and orientation of said hard disk through a track-centering and track-following procedure to account for eccentricity of said hard disk with respect to the center of rotation of said spindle; (c) measuring data from said hard disk with a magnetic read head responsive to a triggering signal; (d) maintaining alignment of said magnetic read head whereby said magnetic read head is positionally located to be driven to a preselected orientation with respect to said hard disk; (e) establishing numerical alignment of said data to account for instability of said triggering signal and said spindle of the spin-stand; and, (f) returning to step (e) prior to a completion of reading said data from said hard disk.
