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
variations in tape speed, yield higher track density and capacity, and provide a multi-channel
architecture for increased transfer rate and performance.
2.3.4 Advanced Partial Response Maximum Likelihood
Improving on Partial Response Maximum Likelihood (PRML) technology traditionally used in disk
drives and communication systems, PRML channel technology, 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.
2.3.5 Advanced Metal Powder Media
Advanced Metal Powder (AMP) media is a state-of-the-art media using durable metal powder
technology for recording very high densities of 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.
2.3.6 Positive Engagement Tape Leader Buckling Mechanism
The positive engagement tape leader buckling mechanism is a highly robust mechanism that increases
data cartridge life and supports the
extensive duty-cycle environments found in high-end and
automation environments.
This mechanism engages the tape leader upon data cartridge load and disengages it upon data cartridge
unload. It uses a solid metal pin attached to the drive leader to link with molded clips permanently
attached to the tape leader inside the data cartridge. The Positive Leader Link design makes the
buckling of Super DLTtape media a totally reliable mechanical process.
