Abstract
Disclosed is a near field optical recording head for use with light from a light source to read data from and to write data to a surface of an optical recording media. The recording head includes a slider body adapted to fly a first distance above the surface of the optical recording media, the first distance being less than one wavelength of the light from the light source. The recording head also includes separate read and write apertures having dimensions which optimize read and write functions, respectively.
Claims15
An optical data storage system comprising:
- an optical recording media providing a surface;
- a source of light producing an optical beam;
- a near field optical recording head forming separate read and write pinhole apertures, the read pinhole aperture receiving the optical beam and focusing the optical beam on the surface of the optical recording media when data is read from the surface, the write pinhole aperture receiving the optical beam and focusing the optical beam on the surface of the optical recording media when data is written to the surface.
