本文的开头即以roller coaster(原指游乐场的环滑车)来比喻1998年科技的迅猛发展。它提到:DVD,the eventual replacement for the videotape,will hitthe shops. 这不由得让我们想起20年来音像类消费电子产品的发展。1976年盒式录象带(VHS)之后,1980年出现了电影光盘(LD),1982年出现了激光唱片即袖珍光盘(CD),1994年出现了视频光盘(VCD),而1996年11月问世的数码视频光盘(Digital Video Disc,DVD),即数码影碟,更引起了全球的轰动。因为,DVD把所有领域的光盘(laser disc)统一提升为更高密度和全数字化,DVD采用和CD或VCD相同的直径的盘片,但可以双面播放,其单面的记录容量为4700兆位,为同面积的CD的7倍。 DVD不但可用于电视、音响和通讯方面,还在计算机的数据存储方面开辟了全新的领域、例如,一张DVD就可储存《围城》那样的书2万多册。 本文虽然略含“言商”气息,但是,若干观点颇有哲学味。令读者耳目一新。如: The products and services that will amaze us this year, in a couple of years willjust be seen as the building block to something better. TV, radio, the telephone, airtravel. All recent arrivals and all marvelous but all now commonplace. 本文的另一个观点也新意扑面: Technolog
The beginning of this article is to describe the rapid development of science and technology in 1998 with the roller coaster (formerly referred to as the playground’s ring block). It mentioned: DVD, the eventual replacement for the videotape, will hitthe shops. This could not help but remind us of the development of audio-visual consumer electronic products for 20 years. After the cassette tape (VHS) in 1976, a movie CD (LD) appeared in 1980, a compact disc (CD) was appeared in 1982, and a video CD (VCD) appeared in 1994, and in November 1996. The advent of digital video discs (DVDs), namely DVDs, has caused a global sensation. This is because DVD has promoted all areas of laser discs to higher density and full digitization. DVDs have the same diameter as CDs or VCDs, but they can be played on both sides with a single-sided recording capacity of 4,700 megabytes. Bit, 7 times the CD of the same area. DVD can not only be used for television, sound and communication, but also opens up entirely new fields in computer data storage. For example, a DVD can store more than 20,000 books like “Fortress Besieged”. Although this article contains a little bit of “words and quotients,” several views are quite philosophical. Make readers refreshing. Such as: The products and services that will amaze us this year, in a couple of years willjust be seen as the building block to something better. TV, radio, the telephone, airtravel. All recent arrivals and all marvelous but all now commonplace. Another point of view is also a new look: Technolog
