A Media Class is an integral part of the media migration 
philosophy. When media type migration or media class 
migration occur, media must stay within the same media 
class. 

Basic Media Class parameters include the Media Class name, 
media type, class capacity, mountable by class, high mark, 
notification comment, and use callbacks and callback 
information.

The Media Class name parameter is a user-specified name by 
which the Media Class is known to the user. Valid Media Class 
names may contain up to 16 characters, including spaces. 
Leading and trailing spaces are not permitted.

The media type parameter identifies the type of media used in 
the Media Class. As noted before, only one media type can be 
specified for a Media Class. 

Media Classes are designed to be associated with multiple 
archives. Media migration cannot occur unless a media class 
spans at least two archives. However, a media class can be 
wholly associated with one archive. 

Therefore, plan Media Class capacities to cover the expected 
size of the archives configured earlier. See the following page 
for an example of two media classes associated with two 
archives.
