   The total number of tracks that a surface can have depends on the drive’s engineering; today’s hard drives may have over 16,000 tracks on each surface. Cylinders:Because all heads are on a single actuator arm, the heads read the same track number on each surface at the same time.

   What is a hard drive made of?

   • Hard drives, also called hard disk drives, hard disks, or fixed disks, consist of several small, identical disks called plattersstacked together and placed in a sealed enclosure to protect them from dust or damage. The platters are made of aluminum or glass, and are coated with a thin layer of magnetic media that stores the actual data.

   What does a hard drive do?

   • Hard disks do one thing well — they provide storage space for data and operating systems. They also give computers the ability to remember things when the power goes out. In this article, we'll take apart a hard drive so that you can see what's inside, and also discuss how they organize the gigabytes of information they hold in files!

   What is an example of a hard disk?

   • A computer's internal hard drive is an excellent example of a hard disk. This disk is typically mounted inside the computer case on top of the power supply unit. The hard disk contains spinning disks (called platters) that store data on their surfaces.

   How does a hard disk drive work?

   • Here is a typical hard-disk drive: It is a sealed aluminum box with controller electronics attached to one side. The electronics control the read/write mechanism and the motor that spins the platters. The electronics also assemble the magnetic domains on the drive into bytes (reading) and turn bytes into magnetic domains (writing).

   What are the characteristics of a hard drive?

   • Characteristics used to rate and compare hard drives include capacity, spin speed, seek time, rotational latency, access time, interface, disk cache, data transfer rate, and data transfer mode. Hard drives connect to a host adaptor on the mother- board or a separate expansion card. They use a specific interface technology in order to communicate.

   What is a hard disk drive?

   • In this chapter, we dive into more detail about one device in particular: the hard disk drive. These drives have been the main form of persistent data storage in computer systems for decades and much of the development of file sys-tem technology (coming soon) is predicated on their behavior.
