Forward-looking: Heat-assisted magnetic recording is a technological breakthrough that has been decades in the making. The first patent describing a method for using heat to record data through a magnetic field dates back to 1954. Seagate began researching "modern" HAMR hard drives in the 1990s. Now, the American manufacturer is finally shipping its first commercially available HAMR hard drives.
In a nutshell: Seagate has started shipping its first HAMR hard disks for data center solutions, bringing the novel storage technology a step closer to mass production and consumer sales. However, traditional PMR and SMR-based recording technologies are not completely obsolete yet.
