• dramatic improvement in track following enables track width reduction • reduce reader width from a few microns to 90 nm • Ultra narrow reader results in a dramatic loss in read
Focus on track density scaling with modest linear density scaling §For track density scaling we need to: –Improve track following –Reduce the reader width from ~1000nm to 29 nm §Ultra narrow reader results in a dramatic loss in read back signal that must be compensated by: –improved media technology à require improved writer technology
We argue that controlling the head–tape interaction is key to achieving high linear density, whereas track-following and reel-to-reel servomechanisms as well as transverse dimensional...
Key issues in the design of magnetic tapes for linear systems of …
Controlling the track spacing problem will require better understanding of tape dimensional stability and how it is influenced by environmental changes, by pack stresses, and by tape design and processing.
Moving a thin tape at high speeds and the mechanical stability in the cross track direction provide engineering challenges for increasing track densities in combination with many parallel channels for high data rates. These issues and trade offs are the main focus of this paper. 1. Introduction.
Scaling tape-recording areal densities to 100 Gb/in 2 - IEEE Xplore
We envision that advancements in media, data-detection techniques, reel-to-reel control, and lateral motion control will enable much higher areal densities. An achievable goal is a linear density of 800 Kb/in and a track pitch of 0.2 µm, resulting in an areal density of 100 Gb/in 2.

Aug 1, 2008 · We argue that controlling the head-tape interaction is key to achieving high linear density, whereas track-following and reel-to-reel servomechanisms as well as transverse dimensional...
Track-following in tape storage: Lateral tape motion and control
Apr 1, 2012 · Improved track-follow capability is crucial to aggressively scale the track density. One of the most important limiting factors in reducing the track pitch is the lateral motion of the flexible tape media.
In this paper, we demonstrate the viability of continuing to scale tape areal density beyond the projections of the INSIC roadmap by performing a single-channel areal density demonstration of 317 Gb/in2 on a new strontium ferrite (SrFe) tape medium.
Side-Reading Effects in High-Track-Density Tape Recording
Jul 15, 2013 · Aggressive track-density scaling in linear magnetic tape recording has been identified as a key means of sustaining capacity scaling. As the reader width decreases, the relative signal contribution of the written track region outside the lateral extent of …
