85年1月在内华达州拉斯维加斯举行的用户电子学冬季展览会生动说明了两种基本相似技术对分散市场力量的反应。以激光读出为基础的声频唱片和视频唱片都使用数字数据读出技术,数据编码成自转光盘凹坑的形式。这种技术已经存在相当一段时间,事实上,1972年末美国音响公司(MCA)曾在纽约展出过原型视频盘唱机了。声频唱片在美国,激光驱动的声频唱机在一年多前就能买到。到1983年为止,唱机的销售量
The User Electronics Winter Show in Las Vegas, Nevada, in January 85 vividly illustrated the reaction of two basic similar technologies to decentralized market forces. Both audio and video recordings based on laser readout use digital data readout techniques, and the data is encoded in the form of pits on spinning disks. This technology has been around for quite some time. In fact, at the end of 1972, the American Audio Corporation (MCA) exhibited a prototype video disk player in New York. Audio recordings in the United States, laser-driven audio players can be purchased more than a year ago. Until 1983, the sales volume of record players
