Abstract:
An assembly for writing/reading high density data on a recording media as a series of tags comprising a magnetic information bit pattern, the assembly comprising:1) a magnetic bias field generator for applying a magnetic bias field on the media;2) a thermal heater for generating and directing an incident thermal wave to the media;3) a first controller for coordinating a mutual positioning of the incident thermal wave and the media for inducing a direct thermal coupling therebetween;4) a magnetic sensor for reading written data on the media; and5) a second controller for coordinating a mutual positioning of the magnetic sensor and the media; the assembly acting as a reader by operating the second controller so that the magnetic sensor is positioned for reading written data on the media; the assembly acting as a writer by operating the first controller and performing at least one of the following actions:i) using an information signal for modulating the magnetic bias field;ii) using an information signal for modulating the power of the incident thermal wave to the media.
