STORE and TurboSTORE/iX Manual

Unlabeled Tapes 

At the beginning of each reel of a STORE tape is the STORE label and a
directory described all of the files stored on the tape.  The directory
contains one entry for each file.  Depending on the number of files being
stored, the directory can span multiple records.  Following the directory
is the directory extension, which contains parallel set information, as
well as the names of HFS syntax files.  This is followed by the first
tape mark on a STORE tape.

The next section of the tape is the data for the files being stored.
Each file begins with a tape mark, followed by a file information record.
This record contains a STORE record header, a file label, contiguous
block information, and an optional file label extension.  This record may
also contain the beginning of the file's data.  If it does not, the
file's data starts in the next record.

At the end of the tape, there are two tape marks, and then a record
containing store trailer information.  Following the trailer are three
tape marks, signifying the end of the media.
