This text explains how hard disk drives operate, how billions of bytes of digital information are stored and accessed, and where the technology is going. In particular, the book emphasizes the most fundamental principles of magnetic information storage, including in-depth knowledge of both magnetics and signal processing methods. Magnetic Information Storage Technology contains many graphic illustrations and an introduction of alternative storage technologies, such as optic disk recording, holographic recording, semiconductor flash memory, and magnetic random access memory.
