Deal with tape drives that can read multiple media types

Enterprise and LTOs can read several types of media: enterprise 55 can read 55 media and JD 60 can read 55 and are compatible with others...

For now we are assigning media by logical libraries but this is very static partitioning an not efficient at all... A drive 55 has to be moved to JD logical library to read these media...

Would be better if the drives could read any media they are compatible with.
