先锋公司的DVR—7000 DVD录像/播放机是首批投放美国市场的DVD录像机之一,它采用DVD—R和DVD—RW格式,以期同标准的DVD播放机和DVD—ROM驱动器有最好的兼容能力。 和CD—R相似,DVD—R是限于只写入一次的录制媒体,一旦录入内容以后,剩余的碟片空间就不好用来再录制其他内容。DVD—R空白碟有两种容量规格:3.95和4.7GB。这两种规格分别提供有两种用途的空白碟片:一种是普通家用型,价格比较便宜;另一种是商用制作型,专门用来制作商品DVD碟片。DVR—7000可使用普通家用型DVD—R空白碟。 DVD—RW是一种重写型的格式,可删除原有的内容后重新写入新的内容,重复
Pioneer’s DVR-7000 DVD Video Recorder is one of the first DVD recorders to hit the U.S. market in DVD-R and DVD-RW formats, with the best of the standard DVD players and DVD-ROM drives Compatible Like a CD-R, DVD-R is limited to recording media that is written once, and once the content is recorded, the remaining disc space is not good enough to record additional content. DVD-R blank discs come in two capacities: 3.95 and 4.7GB. Both of these specifications provide blank discs for two purposes: one for normal home use and the cheaper one, and the other for commercial making, specifically for making DVDs for merchandise. DVR-7000 can use ordinary household type DVD-R blank discs. DVD-RW is a rewritable format that rewrites new content after it has been deleted
