Learn More About HDDs

HDDs use rotating magnetic disks, known as platters, to store data. These platters spin at high speeds while a movable read/write head hovers just above them. As data is read or written, the head adjusts its position to access the correct part of the disk, interpreting or altering the magnetic patterns on the platter to represent data.
