Information record is stored and read on the tape /4/ with optically active layer so that at least one storing and/or recording beam /3/ rotates above the tape /4/, perpendicularly to the tape /4/ and in parallel with the axis of rotation, with the radius of rotation larger than half of the optically active layer on the tape /4/, while the tape /4/ moves straight in the direction along its length. Record is distributed into discontinuous sectors /6/ of tracks in the shape of arcs. Device for carrying up the method has rotating recording head /1/, where the source/reader /2/ is placed for transmission of the beam /3/ in a way according to the invention, whereas the tape /4/ is seated movably, with straight part for the corresponding section /6/ of the recording track, which is perpendicular to the direction of incidence of beam /3/. Preferentially, the tape /4/ is double-sided and the sources/readers /2/ are at least four and are located in pairs, positioned in balance, which are directed for double-sided transmission of beams /3/ to the tape /4/ and fitted with slot /7/. |
