FIELD: information storage. SUBSTANCE: radiation of semiconductor lasers gets into input face ends of optical fibres, each of them optically connected with each of N semiconductor lasers. Optical fibres are made fast to plate-holder in V-shaped recessions placed in parallel. Output face ends of optical fibres are optically connected to information carrier in which plane focused optical spot is formed created with optical focusing element. EFFECT: improved operational characteristics. 4 cl, 3 dwg
