EXB-8205 For the EXB-8205, the following Density Codes are available:

00h Default format

14h 8200 uncompressed format

7Fh Nochangeinformat

90h 8200c compressed format

SCSI-2 Option (Density Code reflects the areal bit density)

When you choose the SCSI-2 option, “density” is interpreted more

strictly to mean the areal density of the bits on the tape. According to

the SCSI-2 option, the EXB-8505 writes and reads in two densities

only: 8500 double-track and 8200 single-track, while the EXB-8205

writes in one density only: 8200 single-track. (This is because data

compression does not affect the density of the bits on the tape.)

For the SCSI-2 option, you do not use the Density Code to control

whether the CTS compresses data. Instead, you set the DCE bit on the

MODE SELECT Data Compression page (Page Code=0Fh) to select

compression.

EXB-8505 For the EXB-8505, the following Density Codes are available:

00h Default density

14h 8200 single-track density

15h 8500 double-track density

7Fh No change in density

If you want to write in 8500c format, select Density Code 15h and set

the DCE bit to 1 when you write LBOT and the first data block. If you

want to write in 8200c format, select Density Code 14h and set the

DCE bit to 1 when you write LBOT and the first data block. If you do

not set the DCE bit to 1, the EXB-8505 writes uncompressed data.

EXB-8205 For the EXB-8205, the following Density Codes are available:

00h Default density

14h 8200 single-track density

7Fh No change in density

If you want to write in 8200c format, select Density Code 14h and set

the DCE bit to 1 when you write LBOT and the first data block. If you

do not set the DCE bit to 1, the EXB-8205 writes data in 8200

uncompressed format.
