PURPOSE:To eliminate mechanical scanning and to attain very high speed access by exciting a light signal, taking out the transmitted light signal or attenuating the transmitted light signal in an optical waveguide loop. CONSTITUTION:The optical waveguide loop LP accumulating and transmitting the light signal is excited by a write means C1 and the light signal is written. The light signal is read through a read means C2 and a signal control means SW attenuates and eliminates the light signal of a prescribed timing, which transmits the loop LP. Thus, an optical storage device which can execute very high speed access can be obtained by constitution which differs from an optical disk and which does not require mechanical scanning. |
