Very small Magneto-Resistive Cluster (MRC) Heads yield data transfer rates
as high as 11MBs.
New High-Efficiency PRML Channel
A newer PRML channel improves on traditional PRML disk drive
technology by bringing new levels of performance and capacity to
LGMR technology and high-performance tape drives. The advanced,
high-efficiency PRML channel used in LGMR was developed jointly
by Quantum and Lucent Technologies. It provides high encoding effi-
ciency recording densities (97 percent efficient) for greater capacity
and performance, which enables Super DLTtape technology to sub-
stantially increase its transfer rates and capacities over current
DLTtape products and other linear tape technologies.
Advanced Metal Powder Media (AMP)
The Advanced Metal Powder media is a vital component of the foun-
dation of Super DLTtape technology. The state-of-the-art AMP media
increases the native capacity of the media to at least 110GB per car-
tridge, offering ease-of-use and lower total cost of ownership. AMP
media uses durable metal powder technology to store very high densi-
ties of data and contain embedded information for the POS system.
Neither magnetic servo writing nor media magnetic pre-formatting
are required for the Super DLTtape system.(See Figure 17-5.)
