DVD+RW与DVD-RW中的符号+-是什么意思
DVD+RW与DVD-RW中的符号+-是什么意思
区别不大,二者都可以刻录.
引用自雅虎问答:
For DVD-RW or DVD+RW,there's a thing called a "wobbly track" which is kind of trick to provide timing information to the writer about just where the disc is positioned.The DVD+RW has much tighter timing than the DVD-RW,so it's possible to do sector-accurate rewriting on a DVD+RW,not so on a DVD-RW.That was considered necessary for a DVD recorder that worked just like a VHS deck.However,Panasonic solved this problem for DVD-R/RW...they simply put a hard drive in their DVD recorder...you could edit on the HDD,then write out to disc.See the link below for more technical discussion,but for most use,it just doesn't matter.
再问: 我问的是那加和减是什么意思
再答: 加减只是历史遗留下来的一个符号,简单说带加号的可以对光盘上不同区间做重新刻录,但是带减号的不行,但是索尼的dvd-rw可以。对于普通消费者而言几乎没有区别。
