Abstract
A reader (12) is provided with: a near-field light device (122) having (i) one or a plurality of quantum dots and (ii) an output end (224) laminated on an upper layer of the one or plurality of quantum dot layers; and a light receiving device (124) which is configured to receive light caused by near-field light formed by the near-field light device upon reproduction of record information on a recording medium. According to the reader, the information recorded by heat assisted magnetic recording can be reproduced without providing a separate magnetic circuit.
Claims3
A reader comprising:
- a near-field light device having (i) one or a plurality of quantum dots and (ii) an output end laminated on an upper layer of the one or plurality of quantum dot layers;
- an energy source supplying the plurality of quantum dots of said near-field light device with energy;
- and
- a light receiving device which is configured to receive light caused by near-field light formed by the near-field light device, which is supplied energy by activated said energy source, upon reproduction of record information on a recording medium.
