User:Nickgb/Magnetic Recording Trilemma

The Magnetic Recording Trilemma is a phrase first coined in the early 2000's to describe the key competing design requirements for magnetic recording, in particular in hard disk drives. Resolution of the trilemma is often mentioned as a background justification for magnetic recording research projects investigating potential future recording systems including heat assisted magnetic recording, discrete track media, bit patterned media, shingled writing as well as basic research into new materials for magnetic disks and recording heads.

The basic requirements encapsulated in the trilemma are the readability, writeability and longevity of recorded data.
