Title: Optical recorder and reproducer
Inventor: HITOTSUMACHI SHIYUUZOU
IPC: G11B7/00
Filed: 1980-08-28
Abstract: PURPOSE:To realize erasing while carrying out reproduction and at the same time to obtain an effect equivalent to the rerecording after erasing, by carrying out the erasing by superposing a DC signal on a record information signal with the intensive light flux during the reproduction time and then reproducing these signals by performing fast forwarding until the information is detected. CONSTITUTION:The current of a power source 2 and modulated by a modulator 1 is applied to a semiconductor laser 3. The beams sent from the laser 3 are focused on a recording surface 6 via a half mirror 4 and a condenser lens 5, and the information is recorded on the surface 6 in the form of a change caused by heat. In the reproduction time, the current of the source 2 is reduced, and the reflected light given from the surface 6 is received at a photodetector 10 to be demodulated by a demodulator 11. For erasion, the current of the source 2 is increased and a DC signal is superposed on a record information signal to be recorded on the surface 6. In the reproduction time, an optical system 8 is quickly forwarded in direction A by a shifter 9 until the information is detected. In such way, erasing is possible while reproducing the part which is once recorded, and at the same time an effect equivalent to rerecording after erasing can be obtained.

IPC: B41F33/14
Filed: 1988-05-18
Abstract: PURPOSE:To restrain the change of tension at the time of a brake change, by detaching a surface brake belt at the time point when a shaft end brake output is stable, and afterward, conducting the feed back control of a shaft end brake. CONSTITUTION:The voltage of an open loop output setting power source 17 is charged to condensors 18, 19 and given as a brake output signal by the changeover of an RY1. After a brake belt having been detached, an RY2 is put 'ON', and the feed back control of a shaft end brake is conducted by means of a time constant setting resistance 20 and the 1st delay circuit decided by the condensor 18 or 19. The changeover of brake is done in the following process: 1, the force of the shaft end brake is made to be the open loop output without feed back and is overlapped with a surface brake force. 2, the surface brake force is detached at the time point when the output of the shaft end brake is stable and afterward, the feed back control of the shaft end brake is conducted. At this time, the open loop output is set at a value in which a target tension is given by means of the shaft end brake alone.
