Abstract: PURPOSE:To obtain an excellent reproduced output through the change in ellipticity due to magnetooptic Kerr effect, by setting the thickness of a magnetic film to a limited one and making an arrangement that no layer, in which absorption is performed, can be installed to one surface of the magnetic film opposite to the substrate side, and using a polarization beam splitter and lambda/4 plate. CONSTITUTION:A magnetic film 5 is installed on the surface of a substrate, for example glass substrate 10, which does not absorb any lights to be used for reproducing and the thickness d1 of the magnetic film 5 is made extremely thin, for instance, 100-200Angstrom . Moreover, the surface of the magnetic film 5 opposite to the substrate 10 side is, for instance, directly exposed to air or covered with a protective film 11 made of SiO2, etc., to prevent a layer in which absorption of lights is performed from producing on the surface. When the thickness of the magnetic film 5 is set to, for example, 150Angstrom , the Kerr ellipticity epsilonk can be increased substantially and reproduction can be performed with a device utilizing the Kerr ellipticity. The reproduction can be performed from either sides of the substrate 10 side and protective film 11 side. The most suitable thickness of the magnetic film 5 can be changed slightly depending on the material, but an excellent result can be obtained when the thickness is set to 50- 300Angstrom .

Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To automatically relight a discharge lamp without recharging a power supply when the discharge lamp goes off because instantaneous failure by resetting a timer for a high voltage pulse circuit during lighting. SOLUTION: When a switch 1 is charged, a timer 2 is activated into an ON state to close a switch circuit 3. An oscillation circuit formed with a capacitor 4 and a choke 5 generates pulse to apply high voltage pulse stepped up by the choke 6 to a discharge lamp 7. When the discharge lamp 7 is lit, a lamp current detection circuit 8 opens a switch circuit 3 to stop the high voltage pulse. When the discharge lamp 7 is not lit because it is damaged or its life runs out, the timer 2 stops the high voltage pulse after a preset time, 30 minutes, e.g. passed. When the discharge lamp 7 is then lit, the lamp current detection circuit 8 holds the timer 2 in a set condition. When the discharge lamp 7 goes off because of instantaneous failure, a power is recovered and then the switch circuit 3 is closed to generate the high voltage pulse so that the discharge lamp 7 can be lit again when cooled.
