Even though a log tape record is made up of multiple records and must be parsed, the
good news is that there typically are a finite number of record types that have to be
parsed (unlike other nonrepetitive records where there are anything but a finite number
of record types that need to be parsed).
Fig. 9.2.6 shows that there are a finite number of records that need to be examined when
parsing a log tape.
