IPC: G11B5/41
Filed: 1987-01-27
Abstract: PURPOSE:To obtain a cleaning tape for a magnetic tape which is a thin film and has excellent light shielding property by laminating a thin film plastic film on the outside surface of which fine ruggedness is formed via an adhesive agent layer to the surface of the vapor deposited metal layer of a thin film plastic film. CONSTITUTION:The plastic film 4 is laminated via the adhesive agent layer 3 on the vapor deposited metal layer 2 of the plastic film 1 having the vapor deposited metal layer 2. The fine ruggedness is formed on the outside surface of either or both of the films 1, 4. The light shielding property is, therefore, obtd. by the vapor deposited metal layer and since the films play the role of a base and cleaning tape, the tape of a desired thickness is obtd. by the thicknesses of the films. The need for exposing the vapor deposited metal layer is eliminated by forming the tape into the laminated structural body and, therefore, the delamination by rubbing of the vapor deposited metal layer is obviated and in addition, the mechanical strength and above all, tear strength by the laminated structure are enhanced.

Abstract: PURPOSE:To precisely stabilize a light source by digitally controlling the stabilization of the light source, precisely converting the status of the light source or the peak value for power supply voltage into a digital value and instantaneously determining the quantity of supply power to the light source from said digital value. CONSTITUTION:Since a photocoupler 301 does not emit light when a transistor (TR) Tr1 turns off, a TR Tr2 is also turned off and power conduct from a rectifier 302 to a halogen lamp 5 is interrupted. When the TR Tr2 is on, the photocoupler 301 emits light, a photodetector is turned on and the TR Tr2 is also turned on, so that power is supplied to the halogen lamp 5. Namely power conduct to the halogen lamp 5 is controlled in accordance with the output level of an output port 02 in a controlling part. The quantity of light emitting can be kept at a prescribed value by digitally controlling the power conduct time to the halogen lamp 5 in accordance with the variation of power voltage by an internal timer.
