PRODUCT DESCRIPTION

The Quantum DLTÔ 7000 tape system is a high-performance, high-capacity, streaming cartridge tape system designed for efficient data back-up for midrange and high-end computing systems. With Quantum’s DLT advanced linear recording technology, a highly accurate tape guide system, and an adaptive control mechanism, the drive is ideally suited for mid-range systems, network servers, and high-end workstations and systems.

Using data compression, the DLT 7000 tape system features a formatted capacity of 70.0 GB* and a sustained user data transfer rate of 10 MB/second* (native capacity is 35.0 GB; native data transfer rate is 5.0 MB/second).

The device is an extended-length, 5.25-inch form factor, half-inch cartridge tape drive. The design includes a four-channel read/write head, Lempel-Ziv (LZ) high-efficiency data compression, and tape mark directory to maximize data throughput and minimize data access time.

The system is available either as an integratible or “embedded” drive or as a tabletop version. The tabletop version is packaged in housing that includes its own cooling fan and power supply, requiring ac power.

The DLT 7000 tape offers the following product features:

  • 35.0 GB Native, 70.0 GB Compressed Capacity (Formatted capacity assuming a 2:1 data compression ratio. Note that actual compression ratio depends on the type of data, SCSI bus limitations, and system configuration.) 35.0 · Superior Error Detection and Correction
  • Extensive Embedded Diagnostic/Self-Test Software
  • Fast access to Data via Tape Mark Directory
  • Tape-Loadable Firmware
