MODE SENSE Block Descriptor List
This field indicates the current operating tape format.
The Density Code value returned in response to a MODE
SENSE command will be as described below:
The density code is set to the principal density code
when the Drive has reported Unit Attention due to
power up or hard reset or when the density of a newly
inserted cartridge is not yet determined. The
principal density code is the highest supported
density supported by the Drive.
SLR7
The highest supported density is ALRF-2
SLR50
The highest supported density is MLR3
SLR60
The highest supported density is ALRF-1
SLR75
The highest supported density is ALRF-1
SLR100
The highest supported density is ALRF-1
SLR140
The highest supported density is ALRF-6
When a successful read/space type command has been
performed the Density Code will be automatically
updated to reflect the format on the tape just
read/written.
Possible Density Codes are:
00h : Unknown
21h : QIC-5010-DC tape format
22h : QIC-2GB-DC tape format
26h : QIC-4GB-DC tape format
30h : MLR3 tape format
32h : ALRF-2 tape format
33h : SLR6 tape format
34h : ALRF-1 tape format
36h : ALRF-6 tape format
This field will always be set to zero to indicate that
the whole tape has the same density code.
