Filed: 1987-02-20
Abstract: PURPOSE:To obtain a reading-out signal of the same quality in terms of a signal to noise ratio even if a wavelength is changed by comparing the spectra before and after recording and making computation such as subtraction or division. CONSTITUTION:An ethanol/methanol mixture into which quinizarin is incorporated is put into a flat glass vessel and is cooled down to an extremely low temp. of 1.8K. A sharp drop of an absorption coefft. arises near the projected wavelength and the spectrum of a recording state is obtd. when light of various wavelength is projected thereto from a dye laser. Reading-out of the record is executed by projecting likewise the light of the dye laser at varied wavelengths. The waveform for the change of the output voltage with time plotting the time at the abscissa and the output voltage at the ordinate is then obtd. This waveform is divided by the waveform for the change of the output with time prior to the recording previously stored in a semiconductor memory. Then, the change rate is larger than the waveform prior to the division and since the fluctuation in the voltage of the low frequency is small, the reproduction signal is easily and exactly obtd. Although the effect of maintaining the specified change rate is small, the exact reproduction signal is obtd.

Title: Reproducing device
Inventor: EGUCHI TAKESHI
IPC: G11B11/00
Filed: 1987-02-19
Abstract: PURPOSE:To attain recording and reproducing with excellent stability, large capacity and high density by providing the titled device with a means for impressing voltage from a probe electrode to a recording medium and a means for reading out the change of current flowing into the recording medium. CONSTITUTION:A reproducing pulse voltage is impressed between a probe electrode 102 and an electrode 103 in a recording medium 1. Since a tunnel current is extremely sensitive to the change of a distance between a metallic probe and a conductive substance when the probe is reached up to about 1nm-several Pm distance by impressing voltage between them, the surface structure of a real space image can be drawn by scanning the probe so as to holding the tunnel current at a fixed value. In addition, various information relating to a surface electronic state can be read out. When the tunnel current is used as mentioned above, a vacuum condition is not required, many merits such that the device can be applied independently of monocrystal or a amorphous state and data can be reproduced with high resolution and low power without being damaged by the current can be obtained. Consequently, >=0.01mum recording resolution can be obtained and high density recording can be attained.
