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