This is not correct.  Record-access in the IBM mainframe world is also
referred to or built on top of an `access method'.  These provide direct
access I/O to the disk at the record level, and the method of address
is of varying complexity.   There may be hash tables, B-trees, etc.,
involved that most certainly do *N*O*T* do byte-stream I/O to the disk.
