FIGURE 2-2 Tape Bar
Tape Bar
The tape bar uses the operator panel display to show the amount of tape that has
been written and read. The tape bar is a configuration option that must be activated
by authorized service personnel. Once activated, it appears on the operator panel
display when the drive is reading or writing.
When the tape bar is activated, the segments and dots simultaneously show the
percentage of the total tape length that has been written and read. Each dot
represents 2% of the tape length; each segment represents 10%.
Write Bar
As data is written to tape, the lighted dots forming the write bar appear at the left
side of the display and advance to the right. The write bar uses the full height of the
display. As the dots fill the display, note that only every other dot is lighted. The
point where the write bar ends is the percentage of tape written.

Note – The tape bar gets its information from the media
information region (MIR) on the tape. The MIR is written to the
tape when the tape is unloaded. If the MIR is bad, the tape bar
does not display. To rewrite the MIR, see
