Title: Magneto-optical recording method
Inventor: SUZUKI YOSHIO
IPC: G11B11/10
Filed: 1987-07-10
Abstract: PURPOSE:To raise the recording sensitivity, and to execute write even at a high speed by generating locally an optical guidance magnetic anisotropy on a magnetic thin film by photoirradiation, and executing the recording. CONSTITUTION:Recording is executed by generating locally an optical guidance magnetic anisotropy on a magnetic thin film by radiating an energy beam. The optical guidance magnetic anisotropy is a magnetic anisotropy which is generated at the time when a light beam has been radiated. It is known that this phenomenon is seen in yttrium-iron garnet to which Si or Ca has been added. In such a way, since energy of a write beam is converted to excitation energy of a magnetic electron as it is, it is unnecessary to raise a temperature of a medium, comparing with a conventional recording system, therefore, write can be executed by a light source of a low output. In such a way, a magneto- optical recording method having high recording sensitivity is obtained.

IPC: H04N5/335
Filed: 1982-09-30
Abstract: PURPOSE:To lead out signal charge flux from each picture element array by providing a charge transfer means with delay characteristics and managing with only one output circuit. CONSTITUTION:Signal charges generated in photosensitive picture element arrays 1-4 in response to incident light are accumulated for a specific time and then moved to transfer means 5 and 6, which transfer them successively. Firstly, the signal charge flux A from the vertical photosensitive picture element array 1 is led out. Then, signal charge flux B from the horizontal photosensitive picture element array 2 is led out. Further, signal charge flux C from the horizontal photosensitive picture element array 3 is delayed by a delay line 12 and led out through the transfer means 5, and signal charge flux D from the vertical photosensitive picture element array 4 follows it. In this case, the delay time of the delay line 12 is so set that the pieces of signal charge flux C and D follow the pieces of signal charge flux A and B from the vertical photosensitive picture elements 1 and 2 without fail, so a serial time-series signal is generated without any overlap between the pieces of signal charge flux B and C; only one output circuit 13 is enough and a signal detection error due to variance in charge/voltage conversion gain and output reference voltage among plural circuits when those circuit generate outputs in parallel is eliminated.
