magtape interface
|
||||
.Sh DESCRIPTION
|
||||
Each tape subsystem has a couple of special devices associated with it.
|
||||
The magtape devices may be on the
|
||||
.Tn MASSBUS
|
||||
using the
|
||||
.Tn TM03
|
||||
formatter,
|
||||
.Xr ht 4 ,
|
||||
or
|
||||
.Tn TM78
|
||||
formatter,
|
||||
.Xr mt 4 ,
|
||||
or on the
|
||||
.Tn UNIBUS/QBUS
|
||||
using either the
|
||||
.Tn TM11
|
||||
or
|
||||
.Tn TE10
|
||||
formatters,
|
||||
.Xr tm 4 ,
|
||||
.Tn TU45
|
||||
compatible formatters,
|
||||
.Xr ut 4 ,
|
||||
or
|
||||
.Tn TS11/TSV05
|
||||
tape formatters,
|
||||
.Xr ts 4 .
|
||||
These devices are typical tape block devices,
|
||||
see
|
||||
.Xr physio 4 .
|
||||
.Pp
|
||||
The conventional device letters/numbers
|
||||
is applicable to any of the transport/controller pairs.
|
||||
(But note that only 1600
|
||||
.Tn BPI
|
||||
is available with the
|
||||
.Tn TS11 ,
|
||||
and that 800
|
||||
.Tn BPI
|
||||
is not applicable to
|
||||
.Tn TM78 . )
|
||||
.Pp
|
||||
When the device last number is between
|
||||
.Em 0-7
|
||||
the device will operate at 800
|
||||
.Tn BPI
|
||||
(or its lowest density), between
|
||||
.Em 8-15
|
||||
it will operate at 1600
|
||||
.Tn BPI
|
||||
(or its second density), and between
|
||||
.Em 16-23
|
||||
it will operate at 6250
|
||||
.Tn BPI .
|
||||
.Pp
|
||||
The rewind devices automatically rewind
|
||||
when the last requested read, write or seek has finished, or the end of the tape
|
||||
has been reached. The letter
|
||||
.Ql n
|
||||
is usually prepended to
|
||||
the name of the no-rewind devices.
|
||||
.Pp
|
||||
.Ux
|
||||
tapes are written in multiples of 1024 byte block
|
||||
records. Two end-of-file markers mark the end of a tape, and
|
||||
one end-of-file marker marks the end of a tape file.
|
||||
If the tape is not to be rewound it is positioned with the
|
||||
head in between the two tape marks, where the next write
|
||||
will over write the second end-of-file marker.
|
||||
.Pp
|
||||
All of the magtape devices may be manipulated with the
|
||||
.Xr mt 1
|
||||
command.
|
||||
.Pp
|
||||
A number of
|
||||
.Xr ioctl 2
|
||||
operations are available
|
||||
on raw magnetic tape.

||||
