Tape Cartridge Compatibility
The 4mm DDS-2 Tape Autoloader is compatible with existing 4mm tape subsystems
that are designed to operate with Digital Data Storage approved media, which meet
the following standards:
For DDS
– American National Standard (ANSI) standard, X3.203-191, Helical-scan
Digital Computer Tape Cartridge, 3.81mm.
– European Computer Manufacturers Association (EMCA) standard,
EMCA-150, 3.81mm Wide Magnetic Tape Cartridge and DDS format.
For DDS2
– European Computer Manufacturers Association (EMCA) standard,
EMCA/TC17/93/20, 3.81mm Wide Magnetic Tape Cartridge for Information
Interchange Helical Scan Recording, DDS2 format.
You cannot change the density setting of the drive because the device reconfigures
itself automatically, depending on the media type installed, as follows:
Media Type
Device Configuration
DDS
Read-only (60m).
DDSllll
Read/write in 2.0GB mode only (90m).
DDS2
Writes 4.0GB, reads in either density (120m).
Non-DDS
Not supported. The cartridge will eject.
Setting the Write-Protect Tab on 4mm Tape Cartridges
The window on the tape cartridge controls write-protection. When the write-protect
tab of a tape cartridge is set (window open), information can be read from the tape,
but cannot be written to it. When the write-protect tab of a tape cartridge is not set
(window closed), information can be both written to and read from the tape. Trying to
write to a 4mm data cartridge with the window open causes an error.
