2.3.2 Pivoting Optical Servo
Pivoting Optical Servo
(POS) is a Quantum-invented, optically-encoded servo
system, which combines high-density magnetic read/write data recording with
laser servo guiding. The POS is designed for 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 current DLT products.

2.3.3 Magneto Resistive Cluster Heads
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 temperature and
humidity, yield higher track density and capacity, and provide a multi-channel
architecture for increased transfer rate and performance.
