Discovering the next generation of hard drives – Global Security Mag Online

Thanks to MAMR (Magnetic Microwave-Assisted Recording) and HAMR (Magnetic Heat-Assisted Recording) technologies, hard disks are now more than 30TB per disk. These two technologies use an additional energy source to optimize the size of the writing head and thus obtain a higher bits and tracks density. However, these are not the only advances of the new generation of hard disks. The perpendicular magnetic recording (PMR), standard for hard disks …
