    摘要: A magneto-optical memory apparatus for enhancing the recording density of a magneto-optical recording medium, thereby to increase its recording capacity. The magneto-optical recording medium having recording marks, each having two ends in which information is recorded. The apparatus also includes an optical head arranged such that at the time of recording onto the magneto-optical recording medium, the recording marks are recorded such that the ends of each recording mark correspond to a second code of digital information composed of two different types of codes; at the time of reproduction, a light beam having a condensing spot is projected to the magneto-optical recording medium and, when a reproduction light containing reproduction information is entered to the optical head from the magneto-optical recording medium, a reproduction signal is supplied; and when the light beam is projected to a recording mark, an information pulse corresponding to the second code is generated in the reproduction signal, only when the reproduction light from the recording mark interferes with the reproduction light from the non-marking part; and a signal detector circuit for detecting the information pulse in the reproduction signal obtained from the optical head and for converting the reproduction signal into a digital reproduction signal.

    摘要: A recording state detecting apparatus is provided with a saturated amplitude detecting unit for detecting a saturated amplitude level of a reproduced signal from a long mark obtained from a magneto-optical disk, an unsaturated amplitude detecting unit for detecting an unsaturated amplitude level of a reproduced signal from an isolation pattern of a short mark and a calculating unit for detecting a recording state (recording sensitivity or amplitude ratio) from the saturated amplitude level and the unsaturated amplitude level. As a result, an accurate recording state, namely, the recording sensitivity or the amplitude ratio of a recording mark can be detected, thereby making it possible to carry out a setting of an optimum recording condition by test-writing, a check on a recording error by verifying, etc. As a result, high-density recording can be realized.

    摘要: An information reproducing device in accordance with the present invention has at least a differentiating zero-cross detection circuit that differentiates analog reproduced signals that were detected as a light beam was irradiated on an information recording medium whereon information is digitally recorded, that generates differentiated signals, and generates binary zero-cross signals by comparing the differentiated signals and its zero level, a gate generating circuit that generates binary gate signals in accordance with the variation of the analog reproduced signals, a flip-flop that generates binary reproduced signals based on the comparison of the zero-cross signals and the gate signals, and an equalizer that emphasizes the high-frequency components of the analog reproduced signals. Provision is made such that the equalizer is installed ahead of the gate generating circuit. The equalizer thus generates gate signals that correspond accurately to the variation of the analog reproduced signals, thereby permitting data recorded on the information recording medium to be reproduced accurately.

    摘要: A plant cultivation method of the present invention includes the steps of: placing a plant under a condition at a pressure of not less than 1.5 atmospheres and not more than 10 atmospheres; and cultivating the plant. A plant cultivation device (1) includes: a cultivation chamber (10); and a compressor (20) which supplies compressed air into the cultivation chamber. A carry-in opening (30), which is provided on a side wall (16) of the cultivation chamber (10) so that a material is carried in/out to/from the cultivation chamber (10) via the carry-in opening (30), is provided with a cover (31) which has a shape that is hemispherical and protrudes toward an inside of the cultivation chamber (10). The cover (31) closes the carry-in opening (30) by being in contact, via a packing (32), with an inner surface of the side wall (16) surrounding the carry-in opening (30). The cultivation chamber (10) has an internal pressure higher than an atmospheric pressure by causing the compressor (20) to supply compressed air into the cultivation chamber (10) in a state in which the carry-in opening (30) is closed. A plant growth rate is improved by cultivating a plant in a high pressure environment which is different from a natural environment. A plant cultivation device is provided for achieving plant cultivation in a high pressure environment.
