Tape Drive Technology
1
The SDLT 600 tape drive 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
600 tape drive system.
Laser Guided Magnetic
Recording
1
The SDLT 600 tape drive systems (shown in
figure 1
) are 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 using servo movement 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.
