Tape Cartridge Compatibility

The 4-mm Tape Drive is compatible with existing 4mm tape subsystems that are designed to operate with Digital Data Storage approved media, which meet the following standards:

ŸFor 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.

ŸFor 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 reconf
itself	automatically, depending on	the	media type installed, as follows:
Media Type	Device Configuration
Non-DDS	Read-only
DDS	Read/write in 2.0GB	mode	only.

DDS2Read in either density; write in 4.0GB mode only.
