Mass storage device employing array of transducers "cocked" in relation to reciprocal movement axis

Abstract

A mass storage device includes a media sheet supported on a substrate for storing digital data bit manifestations and a planar, integrated array of transducers arranged in rows and columns. The array is mounted in registration with the substrate, and its columns of transducers are oriented at an acute angle with respect to a movement axis. A piezoelectric device provides relative movement between the substrate and the array of transducers along the movement axis. Circuitry accesses rows of transducers in each column in a timed manner, so as to operate each transducer in a column at the time the transducer is adjacent a row of stored digital data in the media sheet. The acute angular relationship between the transducer array and the movement axis enables digital data to be stored in the media sheet in a fraction of the surface area occupied by an individual transducer and its associated circuitry.
