Pivoting Optical Servo (POS) is a Quantum-invented, optically-encoded
1
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 (MRC) heads are a densely packed array of
small, cost-effective Magneto Resistive (MR) tape heads precisely
1
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.
Improving on Partial Response Maximum Likelihood (PRML) technology
traditionally used in disk drives and communication systems, Quantum's
advanced PRML channel technology, co-developed with Lucent
1
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 (AMP) media is a state-of-the-art media using
durable metal powder technology for recording very high densities of
1
data. The back side of the AMP media receives a specially formulated
coating to accept the optical servo tracks. Because the servo information is
on the back side of the media, the entire data-bearing side of the media is
available for recording data and eliminates the need for pre-formatting.
In addition, AMP media meets the needs of multiple generations of the
SDLT technology.
The positive engagement tape leader buckling mechanism is a highly
robust mechanism that increases data cartridge life and supports the
