Abstract:

Hard disk drives are all about higher storage capacity and that means higher areal density. Areal density is the product of linear density (density of bits along the tracks) and track density (density of tracks on the disk surface). In this IEEE SV History committee panel session we will examine how hard disk drive track widths have been reduced over over the last 50 years,  while continuing to be the storage behemoths that we still use today.

Over the 50 years of HDD history various ways have been used to try and reduce the track width of the recorded information.  These have included: improved servo technology, creating patterned tracks on the media surface, shingling recorded tracks and general improvements in head and media technology over time.  The panelists will be able to talk about all of these technologies and how they were trying to reduce HDD track width, increase the track density, and provide higher capacity mass storage products.
