Tape blocks are typically bigger than disk blocks.  The block size for
disk is 512 bytes.  The default block size for a VMS tape is 2048 (I
think).  Furthermore the block size on tape can be increased if you want.

The DIRECTORY command reports BLOCKS.  So what is one block on the tape
will almost always be more than one block on disk.  512 character tape
blocks are quite inefficient.  You end up with more blank tape than tape
data on it!
