Filed: 1991-05-16
Abstract: PURPOSE:To eliminate influence of stray light by covering the inside of a package in which a semiconductor laser chip is secured and protected, with a member in which a laser beam is scarcely reflected. CONSTITUTION:Divergent light is converted into a parallel light beam by a collimator lens 110, incident on a hologram element, and the transmitted light is condensed on a recording medium by a condensing optical system to record and reproduce information. A light reflected on the medium is partly diffracted by the hologram element 111, and passed through optical paths 108, 108 by the lens 110, and condensed on a photodetector 105. Thus, a servo error signal is detected, and the information is detected as a reproduced signal. A light 105 radiated outside from a window 102 of a package is emitted to a black nonreflecting member 103, and not then disordered in the package. Accordingly, the incident light on the package is not incident as stray light to a signal detecting sensor 105, but an excellent error signal having a small offset can be detected.

CONSTITUTION:A water tank 7 filled with water 8 is prepared in advance and then it is inverted so that the rubber stopper 9 thereof is abutted against the top end 4a of a metallic pipe 4. When the top end 4a of the metallic pipe 4 is penetrated through the rubber stopper 9, the water 8 in the water tank 7 passes through the metallic pipe 4 to drop down into the interior of a drum 1. In this case, if the capacity of the water tank 7 is made substantially equal to the internal volume of said drum 1, the drum 1 is refilled with the water 8 on a batch basis by mounting the water tank 7 thereon. When terminals 6a, 6b are connected to an external power source and a current is made to flow therethrough to heat a heater 6, the heat is conducted to the water 8 on the periphery of a cylinder 5. Thus, the water 8 in the drum 1 is heated and turned into steam to be discharged outside from small bores 3, 3,... provided on the upper wall of the drum 1 so as to be diffused into air for humidification.
