| 摘要 |
The invention concerns a digital data read/write device, comprising a recording head (10) integral with a moving element (11), which moves above the recording medium (12) provided with several tracks, wherein said 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 both in read and write mode. The guided optical circuit, associated with each microtip: operates, in writing mode as a light guide up to the photosensitive zone of the tip; collects, in reading mode the signal of diffraction of the incident wave on the tip. The guided optical circuits are directly connected to the processing circuits (20) through an optical bus (21).
