MTUG038)
Discontinued as of 31/12/2002.
The 20/40 GB 16-bit 8 mm Tape Drive is a SCSI streaming tape drive that uses 8 mm data cartridges.
The sustained data transfer rate is 3 MB per second.
Features
•
A Liquid Crystal Display (LCD) to provide operating and error messages.
•
Data Compression hardware using an adaptation of IBM's IDRC algorithm which provides an
effective capacity of up to 40 GB of data per cartridge, and an increased effective data rate of 6
MB per second assuming an average Data Compression 2:1, depending on the type of data
transferred.
•
Reads the 8mm tape cartridges in capacities of 2.3GB, 5GB, 7GB and 20GB in native mode or
10GB, 14GB and 40GB in compressed mode.
•
Writes the 8mm tape cartridges in capacities of 20GB in native mode and 40GB in compressed
mode when using Advanced Metal Evaporated (AME) media.
