comprise the DLT-S4 tape drive system.
Description
The DLT-S4 tape drive system is 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.
Magneto Resistive Cluster (MRC) heads are a densely packed array of small
Magneto Resistive (MR) tape heads precisely positioned using advanced thin-
film processing technology.
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 Technologies,
brings new levels of performance and capacity to high-performance linear tape
products.
Advanced Metal Powder (AMP) media is a state-of-the-art media using
durable metal powder technology for recording high densities of data. The
back side of AMP media receives a specially formulated coating to accept the
optical servo tracks, which ensures that the entire data-bearing side of the
media is available for recording data and eliminates the need for pre-
formatting.
The positive engagement tape leader buckling mechanism engages the media
leader on cartridge load and disengages it on cartridge unload. It uses a metal
pin attached to the tape drive leader to link with molded clips permanently
attached to the media leader inside the cartridge.
