DVD-RAM

DVD-RAM, short for Digital Versatile Disc Random Access Memory, is a type of optical disk storage media developed by the DVD Forum and Panasonic in 1995. DVD-RAM is capable of storing large amounts of data and has a storage capacity greater than standard CDs and DVDs, making it a popular choice for backing up large files such as images, audio, or video.

DVD-RAM utilizes an specially designed disc that features an additional layer of plastic that is used to store magnetic information on it. It is also capable of editing, meaning the media can be previously recorded in order to erase or add information. The disc also has a built-in defect management system that allows it to self-repair if part of the data on it becomes corrupted.

DVD-RAM supports fast data access speeds, up to 540MB/s of read speed, and is great for large files or when multiple users access the same disc. Additionally, DVD-RAM is quite reliable compared to other types of media, especially when used in professional applications, and is resistant to scratches for shorter life span than other media.

DVD-RAM discs are available in a number of formats including 4.7 GB single-sided, 9.4 GB dual-sided, and 18.2 GB dual sided which makes them great for high-capacity data storage such as HD video and audio recordings. They are also compatible with the DVD-Video, Video CD, and Super Video CD formats.

Overall, DVD-RAM is an excellent choice for people who need to store large or sensitive files and need reliable access. Despite their higher storage capacity however, DVD-RAM discs are not as popular as other media due to their higher price and limited backwards compatibility with older optical drives.
