Detailed explanation-1: -The Differences Between DVD-ROM and DVD-RAM Generally, DVD-RAM is used to store data, and DVD-ROM is used for movies and supplementary music presentations. The DVD-RAM is read and write, while the DVD-ROM is read-only. This means that once the data is encoded, the disc is in a fixed state and cannot be changed.
Detailed explanation-2: -The main difference between DVD R and DVD RW is that the R is a write-once format. Data can be burned on the DVD only once. On the other hand, data on an RW disc can be erased and rewritten several times. Both DVD R and DVD RW come in +/-formats.
