Perpendicular Magnetic Recording (PMR)

Perpendicular Magnetic Recording (PMR) is a technology used in hard drives to store data more densely. It aligns magnetic bits vertically (perpendicular) rather than horizontally, allowing more bits to fit in the same space. This increases storage capacity and improves data stability and reliability. Essentially, PMR enhances how much information a hard drive can hold by changing the orientation of magnetic particles on the disk surface, making it an efficient and effective way to boost storage performance in modern drives.
