2.3.1 Laser Guided Magnetic Recording
The SDLT system (
) 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.
