Introduction¶

The ND Gigatape System (ND GTS) is a revolution in backup technology, giving vast savings in time, money, and operator effort. ND GTS satisfies the demand for inexpensive, convenient backup of magnetic disks.
The ND GTS is a high-performance, high-capacity tape system that uses 8 mm cartridge tapes and can store up to 2.2 GBytes of data on a single cartridge. This tape system uses standard SCSI as the interface.

Features¶

Helical-scan recording method
Standard 8 mm removable tape cartridge
Up to 2.2 GB capacity per tape
5 1/4 inch full-height size
SCSI controller
Advanced error detection and correction
High MTBF
246 KB/sec data-transfer rate

Product Description¶

The ND Gigatape System is a removable, rewritable-medium tape system that provides reliable and efficient backup for the users. The 2.2 GB capacity tapes and the necessary software allow copying of several disks onto one tape, thus saving a significant amount of storage space. The high recording density is achieved by employing advanced helical-scan recording technology.
ND GTS affords high reliability since it uses advanced Error Correction Code (ECC), and the read-after-write technique.
The medium for the ND GTS is the standard 8 mm cartridge tape whose compact physical size and large storage capacity gives significant savings in storage space compared to traditional magtapes.
