Perpendicular Magnetic Recording

Perpendicular Magnetic Recording (PMR) is a technology used in hard drives to store data more efficiently. It aligns magnetic particles vertically (perpendicular) to the surface of the disk, rather than horizontally. This vertical orientation allows for greater data density, meaning more information can be stored in the same space, resulting in larger storage capacities. PMR uses a specialized read/write head that writes data to the disk with high precision. Overall, this technology improves data storage capacity, speed, and reliability in modern hard drives.
