Erasable optical disks are optical disks that can store data and also be written over and erased multiple times. These disks can store a range of information, just like other types of removable storage mediums.

There are several uses of erasable optical disks. The simplest and most popular one is used to back up data. For example, if you are using a computer and have data that you don't want to lose or don't want to take up too much space on your computer, you can back it up on an erasable optical disk and store it away for safekeeping.

Another use for this type of disk is to transfer data. For example, if you want to share a file with someone else, you can burn the file or files onto an erasable optical disk and then mail or hand-carry it. This has the advantage of being much faster than sending files over the internet.

Finally, erasable optical disks can also be used for archiving purposes. For instance, if you want to keep a file or files of something for a period of time without having to re-write them, an erasable optical disk is an ideal solution. This way, the data can be accessed and retrieved at any time.

Overall, erasable optical disks are highly useful and versatile. They offer an easy way to back up, transfer and archive data. Whether you are a home user or a business user, they are a great storage medium that is convenient, easy to use and cost-effective.
