High-density indicator
The high-density indicator is lit whenever the magnetic tape
drive is operating in the group code recording (GCR) mode.
GCR refers to the specific density of data as it is recorded on
the tape, which is measured in bits per inch (bpi). The tape
drive operates in 1600 bpi Phase Encoded (PE) or 6250 bpi
(GCR) modes. The default for writing is 1600 bpi. There is
no default for reading because the system checks the speed
and reads it accordingly.
