+NAME		tap -- DEC/mag tape formats
+.sp
+.ti 0
+DESCRIPTION	The
+DECtape command tap___ and
+the magtape command mt__
+dump and extract files to and
+from their respective tape media.
+The formats of these tapes are the same except
+that magtapes have larger directories.
+.sp
+Block zero of the tape is not used.
+It is available to contain a boot program to be
+used in a stand-alone environment.
+This has proved valuable for DEC diagnostic programs.
+.sp
+Blocks 1 through 24
+for DECtape (1 through 146 for magtape)
+contain a directory of the tape.
+There are 192 (resp. 1168) entries in the directory;
+8 entries per block;
+64 bytes per entry.
+Each entry has the following format:
+.sp
+.in +3
+path name	32 bytes
+.br
+mode		1 byte
+.br
+uid		1 byte
+.br
+size		2 bytes
+.br
+time modified	4 bytes
+.br
+tape address	2 bytes
+.br
+unused		20 bytes
+.br
+check sum	2 bytes
+.sp
+.in -3
+The path name entry is the path name of the
+file when put on the tape.
+If the pathname starts with a zero word,
+the entry is empty.
+It is at most 32 bytes long and ends in a null byte.
+Mode, uid, size and time modified
+are the same as described under i-nodes (see file system (V))
+The tape address is the tape block number of the start of
+the contents of the file.
+Every file
+starts on a block boundary.
+The file occupies (size+511)/512 blocks
+of continuous tape.
+The checksum entry has a value such that
+the sum of the 32 words of the directory entry is zero.
+.sp
+Blocks 25 (resp. 147) on are available for file storage.
+.sp
+A fake entry (see mt(I), tap(I))
+has a size of zero.
