SDLT 220/320 Technology
SDLT incorporates various new state-of-the-art technologies that contribute to the
SDLT architecture. Some of these ideas are trademarked, others are patented. The
following subsections introduce the important technologies that together, comprise
the SDLT tape drive system.
2.3.1 Laser Guided Magnetic Recording
The SDLT system (
Figure 2-1
and
Figure 2-2
) is based on Quantum’s Laser
Guided Magnetic Recording
(LGMR) technology. LGMR provides a unique
combination of the best optical and magnetic technologies, which results in
dramatically higher capacities by substantially increasing the number of recording
tracks on the data-bearing surface of the media. By recording data magnetically on
the data-bearing side of the media and servoing optically on the backside, LGMR
optimizes highly proven technologies to deliver the most efficient, reliable and
scalable data backup solution to the mid-range market.
