Title: High-density magnetooptic playback head
Inventor: HATAKEYAMA IWAO
IPC: G01R33/032
Filed: 1984-04-20
Abstract: PURPOSE:To detect the fine recording bits on a recording medium with high sensitivity and high SN ratio by coupling polarized light by an optical system to an optical waveguide, making said light incident on the thin magnetic film and conducting the light receiving a magnetooptic effect by the thin magnetic film to a photodetector by the optical system. CONSTITUTION:The optical waveguide consisting of a core 52 and a clad 54 is formed on a head substrate 50. A high refractive index material layer 56 is formed atop the core 52. A head core 58 consisting of the soft magnetic film is formed in the part where the optical waveguides of the end face 50A of the substrate 50 intersect. A mirror 62 which returns the reflected light to the exit end on the opposite side with the core 58 in-between is provided to the incident end 60 of the optical waveguide. The head is used with the material layer 56 side as a magnetic recording medium side and the core 8 perpendicularly or obliquely to the surface of the recording medium. The polarized beam is coupled from the incident end 60 to the optical waveguide and is reflected by the core 58. The reflected light beam returned by reflecting on the mirror 62 is taken out of the incident end 58 and is coupled to the photodetector via an analyzer not slown. The detection with the high sensitivity and high SN ratio is thus made possible.

Title: Magnetic recording and reproducing device
Inventor: NARITA YOSHIO
IPC: G11B15/087
Filed: 1995-04-05
Abstract: PURPOSE: To facilitate the program searching of a tape by providing the frequency regions, such as frequency regions lower than the frequency regions of a tracking control signal, which are not used, with program searching signals for program searching of the tape. CONSTITUTION: The signal of the frequency lower than the frequency of a pilot signal is formed in an oscillation circuit 4. This signal is compared with the reference signal from a reference signal generator 1 by a phase comparator 2. The error signal obtd. in such a manner is suppressed of an unnecessary high-frequency component by an LPF 3 and the output of the oscillator 4 is controlled by the prescribed frequency. The program searching signal 5 formed in such a manner is suppressed of the unnecessary frequency component by a BPF 6 and is then added together with a recording video signal 8, a recording sound signal 9 and a recording pilot signal 10 by an adder 7. The added signals are further amplified by a recording signal amplifier 11 and are recorded on the same track on a magnetic tape 13 via a magnetic head 12.  The influence on image quality, sound quality and tracking performance is lessened if the program searching signals are so controlled by an oscillation control 14 as to be recorded only in the parts where the program searching of the tape is needed.

IPC: G02C7/12
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To cut unnecessary external cut and to obviate the occurrence of the eye's fatigue in VDT work by using polarizing plates capable of arbitrarily changing the extinction direction of polarized light on lens portions. SOLUTION: A frame 1 which is a structure of spectacles is attached with rotary rings 2. Glasses 3 stuck with the polarizing plate are fitted into these rings. A user wears the spectacles at the time of using a liquid crystal display and searches the point where the image of the liquid crystal display is brightest by rotationally the rings 2 to rotate the polarizing plate, thereby making the polarization direction the same as the polarization direction of the polarizing plate of the liquid crystal display. The procedure is carried out with the right and left eyes. Since the directions of the polarized light of the right and left polarizing plates are always the same, the right and left rings may be provided with gears such that both rotate together.  As a result, the influence of the external light may be confined to <=50% and the same effect as the effect obtainable when the brightness of the liquid crystal display is made twice higher is obtd.
