Abstract:
An assembly for writing/reading high density data on a recording media comprising a magnetic information bit pattern, the assembly comprising:1) a plurality of media probes wherein each probe is selected from the group consisting of a thermal heater for generating and directing an incident thermal wave to the media for enabling reading and/or writing, and, a magnetic sensor for enabling reading and/or writing; 2) a magnetic bias field generator for applying a magnetic bias field on the media; 3) a position controller for coordinating a mutual positioning of an enabled probe and the media for inducing a direct thermal coupling therebetween; 4) a control electronics for: (i) addressing a media probe for enabling and coordinating its reading and/or writing; and (ii) coordinating parallel or quasi-parallel reading and/or writing with an array of media probes by instruction to the position controller; the assembly acting as a writer by realizing at least one of the following actions per media probe: a) using an information signal for modulating the magnetic bias field; b) using an information signal for modulating the power of an incident thermal wave to the media; the assembly acting as a reader by operating the position controller vis a vis a preselected media probe.
