A notebook hard drive operates in basically the same manner as those designed for a desktop computer. Data is recorded onto a disc, called a platter, which is housed inside a sealed unit. These platters are made from either glass or aluminum, with a thin layer of magnetic material on the outside.
A notebook hard drive typically uses two electric motors. One motor spins the platter, while the other one operates the head assembly. As the disc spins, the head reads the magnetically embedded data and converts it to readable information on the computer screen.
The notebook hard drive has come a long way since the laptop was first introduced. Most laptop computers use hard drives that can store anywhere from 120GB to 500GB of data. As technology becomes more advanced, hard drives with terabyte capacities will undoubtedly be the norm.
