IPC: G11B7/0045
Filed: 1986-02-21
Abstract: PURPOSE:To attain the easiness of the alignment of a write optical system by using the zero-th order light from an AO element for luminous flux for recording a signal. CONSTITUTION:A beam 16 irradiated from light source 15 such as a laser is divided into the zero-th order light 18 and a diffracted light 19 by an AO modula tion element 17. An electric signal to be recorded from a signal source 20 is converted into a high frequency signal whose voltage is modulated by a high frequency generator 21 and inputted to a transducer fixed to the AO element 17 to generate an ultrasonic wave. The ultrasonic wave propagates in the AO element, a layer whose refractive index differs from that of other layer is formed in the AO element to diffract the beam 16. Since the intensity of the high frequency signal is changed by a recording signal from the signal source 20, the intensity of the ultrasonic wave produced by the transducer is changed according to the intensity of the recording signal. In using the zero-th order light in this way, since the zero-th order light progresses in the same direction as the luminous flux made incident into the AO element different from the element for the diffracted light, the alignment of the optical system including the AO element is attained easily.

Abstract: PURPOSE:To obtain a device which vapor-deposits a ferromagnetic material efficiently by vapor-depositing slantingly the ferromagnetic material on a tape type base which moves slantingly along a belt from a vapor-depositing source arranged under a cooling can and a small roller. CONSTITUTION:While the tape type base 22 from a payoff roll is conveyed from the can 21 by the flexible endless belt 27 extended around the small roller 26, a vapor-deposition beam 24 reaches the base while moving in an area where it is not cut off by an oblique mask 25. Consequently, the ferromagnetic material is vapor-deposited slantingly on the tape type base 22. In this case, the vapor-deposition beam 24 corresponding to an angle beta among vapors liberated from the vapor-depositing source 23 is vapor-deposited on said tape type base 22, but the angle beta is larger than any other conventional angle. Namely, this method remarkably improves the efficiency of vapor deposition.
