| abstract |
The invention relates to a device for writing / reading digital data, comprising a recording head (10) integral with a mobile unit (11), which moves above a recording medium (12). provided with several tracks, in which this head (10) comprises several microtips (13) operating in parallel, each associated with a guided optical circuit, which address the tracks of the recording medium (12). Each microtip (13) operates in both write and read modes. The guided optics circuit, associated with each tip: - behaves, in write mode, like a light guide to the photosensitive area of the tip, - collects in read mode the diffraction signal of the wave incident on The point. The guided optics circuits are connected directly to processing circuits (20) through an optical bus (21). |
