Abstract
A method for patterning a recording medium selectively thermally couples a recording medium and a heat source to alter a chemical composition of the recording medium. An apparatus for patterning a recording medium has a heat source for generating and directing an incident thermal wave to a recording medium so as to alter a chemical composition of the recording medium, and a controller for coordinating a mutual position of the incident thermal wave and the recording medium for inducing a direct thermal coupling between the recording medium and the heat source.
Claims13
An apparatus for patterning a recording medium, comprising:
- a heat source for generating and directing an incident thermal wave to the recording medium said thermal wave altering a chemical composition of a recording medium;
- and
- a controller for coordinating a mutual position of said incident thermal wave and said recording medium so as to thermally couple said heat source and said recording medium.
A read/write head assembly, comprising:
- a read/write head;
- a heat source connected to said read/write head for generating and directing an incident thermal wave to a recording medium, said thermal wave altering a chemical composition of the recording medium;
- and
- a controller for coordinating a mutual position of said incident thermal wave and said recording medium so as to thermally couple said heat source and said recording medium.
