| 摘要 |
An optical reproducing system for reading out magnetically recorded data comprises an optical head (4,4a,4b,4c,4d) for copying magnetic pattern on a magnetic recording medium like a magnetic tape (1), a conversion system (5,6,7,8,9,10) for converting a magnetic pattern on the optical head (4 et al.) to an optical pattern by using the Faraday effect which rotates a polarization of an LED beam (light emission diode) or a laser beam according to magnetic polarity in a domain in said optical head, a charge coupled device (3, CCD) with a plurality of cells for converting beam energy polarized according to recorded data to correspond to electrical output signal. The CCD device effects the conversion or reading of a plurality of data simultaneously.
