The plastic and shining disc is fragile and easy to be disrupted. For example, you may need one disc to be played on the cumbersome DVD player in living room and also need a copied DVD folder/ISO file for playback on the computer in your bedroom upstairs. Sometimes you may want to have several DVD copies for watching in different places. Sometimes when you rent DVDs from DVD providers like Netflix you may want to keep a copy of the rented movie for later watching. Though manufacturers claim that the life spans of DVDs ranges from 30 to 100 years, it is almost impossible under the recommended storage conditions to avoid degradation. A DVD folder is a folder that contains DVD movie content and the video streams of a DVD are stored in the folder named as VIDEO_TS. A DVD ISO file is an image file that contains all of the data found on a DVD disc. All of these together with the last paragraph talk about the physical formats of DVDs.Īlso, there are two digital formats of DVDs - ISO files and DVD folders, both of which can be attained by copying DVD discs.
DVD+R/RW are formats supported by Philips, Sony, Dell, Yamaha and others while DVD-R/RW/RAM are supported by Panasonic, Toshiba, Apple, Hitachi, NEC, Pioneer, Samsung, Sharp as well as DVD Forum.ĭVD+R and DVD-R: they are a recordable DVD format that can record data only once and then the data will be permanently saved on the disc.ĭVD+RW and DVD-RW: they are a re-recordable format and the data on them can be erased and recorded for many times without damaging the discs.ĭVD-RAM: it is a kind of disc that can be overwritten many times but it is only supported by a small proportion of DVD drives.īesides the above DVDtypes, there are also DVD+R DL and DVD-R DL that are Dual Layer writeable DVD+R and DVD-R which can hold more data than those single-layered discs. You may have heard of DVD+R, DVD+RW, DVD-R, DVD-RW and DVD-RAM. The former features a 4.7 GB storage capacity which is the reason we call it DVD-5, and the latter is capable of storing between 8.5-8.7 GB from which we name it as DVD-9. DVD movie discs can be single-layered and double-layered.
