Recently, the Yunnan Provincial Department of Commerce held lectures on “television recordings and CD-ROMs” several times and performed actual program performances among some staff members of the provincial Communist Party of China and agencies of the Ministry of Finance. The response to “television recordings and CDs” was relatively large. So, what are TV and CDs? When placing recordings with images and audio signals on dedicated phonographs, the images and accompanying sounds will be reproduced in concert with laser-recorded audio recordings. People call them TV recordings. “An album with images.” “Laser and television recording (Machine)” has only had a history of more than 10 years from research and development abroad. It has high quality images and sounds, and can perform fast, slow, still images, step forward, and random search. Repeating a certain special trick function during the period is unmatched by ordinary tape players. Therefore, it is an advanced equipment for education, training, intelligence and data access, and culture and entertainment. In addition, the laser recorder can also be interfaced with an electronic computer and can be used for a variety of purposes.
