Advanced Partial
Response Maximum
Likelihood
1
Improving on Partial Response Maximum Likelihood (PRML) technology
traditionally used in disk drives and communication systems, advanced
PRML channel technology, co-developed with Lucent 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
Media
1
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.
Positive Engagement
Tape Leader Buckling
Mechanism
1
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.
Modular Design
The SDLT 600A tape drive is designed as a total system. The system
includes a complex interaction of a number of important components
including such items as the tape path, tape heads, media, data cartridge,
and host interface.
