Tape Drive Technology
SDLT 600A Product Manual

Laser Guided Magnetic
Recording
1
The SDLT 600A tape drives 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
retrieval solution to the mid-range market.
Pivoting Optical Servo
1
Pivoting Optical Servo (POS) is an a Quantum-invented, 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.
which allows Quantum to provide a track count with an order of
magnitude increase over previous products.
Magneto Resistive
Cluster Heads
1
Magneto Resistive Cluster (MRC) heads are a densely packed array of
small, cost-effective Magneto Resistive (MR) tape heads precisely
positioned using advanced thin-film processing technology. SDLT MRC
heads provide high wafer usage efficiency resulting in low head costs, are
less susceptible to variations in tape speed, yield higher track density and
capacity, and provide a multi-channel architecture for increased transfer
rate and performance.
Advanced Partial
Response Maximum
Likelihood
1
Improving on Partial Response Maximum Likelihood (PRML) technology
traditionally used in disk drives and communication systems, advanced
PRML channel technology,, co-developed with Lucent Technologies,
brings new levels of performance and capacity to high-performance
linear tape products. This provides high-encoding efficiency recording
densities for greater capacity and performance that enables SDLT to
increase transfer rates and capacity substantially.
Advanced Metal
Powder Media
1
Advanced Metal Powder (AMP) media is a state-of-the-art media using
durable metal powder technology for recording very high densities of
