Head – The device that reads and writes the information—magnetic or optical—on the disk surface.
The device that reads and writes the information-magnetic or optical-on the disk surface is called the head.
Disk drive.
Hard drive
It is a device or component that reads a video recording, like a DVD/VHS player, and sends the information to a display device like a TV. A video input device can also be a camera that records video and sends the information to a storage device and can also display the captured images on a TV.
In the drive mechanism the part that does this is the head assembly.
A disk drive.
HKLM\Hardware
access port
Per "Guide To Managing and Maintaining Your PC, Seventh Edition" text book by Jean Andrews: (Page 707) Device Manager reads data from the HKLM\Hardware (hkey_local_machine) key to build the information it displays about hardware configurations.
disk derive
A machine that reads data from and writes data onto a disk. A disk drive rotates the disk very fast and has one or more heads that read and write data.There are different types of disk drives for different types of disks. For example, a hard disk drive (HDD) reads and writes hard disks, and a floppy drive (FDD) accesses floppy disks. A magnetic disk drive reads magnetic disks, and an optical drive reads optical disks.Disk drives can be either internal (housed within the computer) or external(housed in a separate boxthat connects to the computer).
