What Does Write-Once, Read-Many Mean?
Write-Once, Read-Many (WORM) is a data storage technology mechanism that stores unerasable and/or unmodifiable information after it has been written on a drive. The data is stored on WORM devices. These device disks store data in a non-rewritable format to prevent users from accidentally erasing or altering sensitive information.

Techopedia Explains Write-Once, Read-Many
Created in the late 1970s, a WORM device is a type of optical media commonly used for archiving information or hosting data archives. This useful data is written on a disk only once, which is useful because archive creators or gatekeepers typically seek information that has not been altered or modified from the original source.
