Tape Drive Technology
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.
2.3.1 Laser Guided Magnetic Recording
The SDLT 600 tape drive systems (shown in
Figure 2-1
) are based on 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.
2.3.2 Pivoting Optical Servo
Pivoting Optical Servo (POS) is an optically-encoded servo system, that combines high-density
magnetic read/write data recording with laser servo guiding. The POS provides high-duty-cycle
applications, which decreases cost and increases user convenience. The POS enables the head to track
dynamic variations in tape motion.
