Tape Drive Technology

1

The DLT-S4 tape drive incorporates state-of-the-art technologies that 

contribute to the SDLT architecture. Some of these ideas are trademarked, 

others are patented. 

 lists some of the important technologies that 

comprise the DLT-S4 tape drive system.

Table 2   Tape Drive Technology

Laser Guided 

Magnetic Recording

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 Heads

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. 

Advanced Partial 

Response Maximum 

Likelihood

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 Media

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.

Positive Engagement 

Tape Leader 

Buckling Mechanism

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.
