v K identifies the Extended High Performance Cartridge Tape
See “Unlabeled Tape Facility” on page 35 for more information.
Note: If the 3494 Tape Library has more than one type of tape drive, all cartridge
tapes should have a media-type label (see Figure 22 on page 23).
Cartridge Tape Requirements (3490E & 3590 Tape Drives)
Figure 23 shows the following 3490E and 3590 cartridge tape requirements:
v The cartridge tape
1
must have an external volser label
2
applied.
v
The write-protect switch
3
must be set to the correct position for the
cartridge’s intended purpose (see “Cartridge Tape File Protection (3490E and
3590 Tape Drives)”).
v
The leader block
4
on the tape cartridge must be seated before inserting the
cartridge into the 3494 Tape Library.
v The tape cartridge must be inserted into the 3494 cartridge storage cells in the
direction
5
shown so that the external label is readable when stored.
Note: When inserting the tape cartridges into the convenience I/O station, insert
the label side first in the direction
6
.
Cartridge Tape File Protection (3490E and 3590 Tape Drives)
Each cartridge tape includes a write-protect switch (
3
in Figure 23) that, when set
to the write-protect position, prevents either writing data to the tape or erasing
data from the tape.
Normally, cartridges used in the 3494 Tape Library should not be write-protected
manually. If required, software can be used to write-protect the cartridges. This
allows the host, when appropriate, to identify a cartridge that no longer contains
current data and can therefore be used as a scratch cartridge. Do not write-protect
scratch cartridges as new data cannot be written to write-protected cartridges.

Cartridge .
Cartridge Tape Labels (3490E and 3590 Tape Drives)
Each cartridge tape in the 3494 Tape Library must have external labels that are
operator- and device-readable. The labels identify the volser and the cartridge type.
