Specifications
o Integrated Single-ended SCSI-2 interface
o Reads and Writes DDS-1 and DDS-2 formats dependent on the mounted tape dimension:
• 60 meter tape - DDS-1 = 1.3 Gbytes
• 90 meter tape - DDS-1 = 2.0 Gbytes
• 120 meter tape - DDS-2 = 4.0 Gbytes With Data Compression enabled.
The above capacities will increase from 2 to 4 times the non-compressed capacities. The average
data compression factor is 2 to 1.
o 1 Mbyte Data Buffer
o Switch or program selectable on-board DCLZ data compression
o Automatic Error correction and detection
o Downloadable firmware
o Asynchronous burst data transfer rate = 3.0 Mbytes/sec.
o Synchronous burst transfer rate maximum = 7.5 Mbytes/sec.
o MTBF = 200,000 power on hours at a 12% duty cycle
o Executes self-test at power on
o Inquiry Vendor Identification String = HP
o Inquiry Product Identification String = C1533A
o Inquiry Product Revision Level String = HP00
