菲利浦资料系统1978年介绍了一种新型光学记录系统。它在贮存能力、资料检索速度和耐用性上都比通常计算机应用的磁盘系统为优越。这是世界上第一个二极管激光光学记录系统。这个系统所应用的预刻槽的双面塑料盘可以贮存相当于500000页打字纸的信息量。资料的检索时间平均约为250毫秒,使圆盘上的任何资料实际上瞬息可得。激光在光学资料记录方面的能力已经了解多年,但是在工艺水平上的突破必须进行多方面探索。菲利浦因为与原有的视频长演示系统相平行地研制,出色地完成了这些突破。菲利浦研究室的K.Bulthuis博士说,“我们唯一所需要的是在二极管激光器方面的突破,这是来自本公司的半导体运转能力,加上与之相匹配的记录材料所致”。专为这个系统所研制的小型AIGaA。双异质结(DH)型二极管激光器,应用0 .1毫米,的半导体小晶片,所产生的脉冲光,其功率与大的气体激光器及其附属调制器者相同。 Philips Data Systems 1978 introduced a new type of optical recording system. It is superior to storage systems, disk systems for computer applications in terms of storage capacity, data retrieval speed and durability. This is the world's first diode laser optical recording system. The pre-grooved double-sided plastic tray used in this system stores the amount of information equivalent to 500,000 sheets of typing paper. Data retrieval time averages about 250 milliseconds, making any information on the disk virtually instantaneous available. The ability of lasers to record optical data has been well understood for years, but breakthroughs at the technological level must be explored in many ways. Philips made these breakthroughs well by developing in parallel with the original video length demo system. “The only thing we need is a breakthrough in diode lasers, which comes from the company's semiconductor capabilities, coupled with matching recording materials,” said Dr. K.Bulthuis from the Phillips Lab. . Small AIGaA developed specifically for this system. Double heterojunction (DH) type diode laser, the application of 0.1 mm semiconductor chip, pulsed light generated, the power and large gas lasers and their affiliated modulator are the same.
