Abstract: The invention is directed to a data storage medium that includes a plurality of servo bands distributed across the data storage medium and a plurality of data tracks positioned between each of the plurality of distributed servo bands. The data storage medium comprises a servo band pitch of less than 200 micrometers. The large number of servo bands distributed across the data storage medium with a relatively small servo band pitch reduces the influence of media dimensional instability. In this way, the invention may substantially increase data read head positioning accuracy, especially in the case of narrow track widths. A read head array arranged in a two-dimensional matrix that includes a first servo read head, a second servo read head, and a plurality of data read heads positioned between the first and second servo read heads may be applied to a data storage medium as described herein.

Abstract: A self-contained imaging sheet comprising in order:(a) a support;(b) a first layer comprising photosensitive microcapsules having an internal phase, said internal phase comprising an image forming agent and a photosensitive composition which undergoes a physical transformation in response to exposure to actinic radiation;(c) a second layer comprising a developer material; and preferably(d) a third layer comprising an adhesive forming component, said self-contained imaging sheet being useful in forming images on plain paper by a process which comprises imagewise exposing said imaging sheet to actinic radiation, forming an image on said developer material, transferring the image bearing developer layer to said plain paper, and separating said imaging sheet from said plain paper, wherein said image bearing developer layer remains adhered to said plain paper and said microcapsule layer remains adhered to said support.
