Modular Design

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

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.

	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.
