PCT No. PCT/FR96/00777 Sec. 371 Date Nov. 24, 1997 Sec. 102(e) Date Nov. 24, 1997 PCT Filed May 23, 1996 PCT Pub. No. WO96/37887 PCT Pub. Date Nov. 28, 1996An optical mass storage device such as an optical disc is described, which includes a light-sensitive layer (1) with elementary cells distributed over its free recording surface (10), in which data is recorded. The device is characterised in that it includes, for each elementary cell, a light guide portion (3) which forms a single-mode optical fiber of a photorefractive material, substantially orthogonal to the free recording surface (10) A structure obtained by Lippmann effect, and formed of stacked individual periodic laminations having the same orientation as that of portion (3), is recorded in the fiber. The light-sensitive layer (1) is arranged on a transparent substrate (2). |
