 | | Purely optical disk drives often are used as a secondary form of storage, but the computer to which they are connected is likely to use a magnetic storage medium for primary disk storage. | | | Data on a disk is read by passing the head back over the surface of the disk; as the head encounters changes in the stored magnetic field, it generates a weak electrical current that indicates the presence or absence of flux transitions in the originally recorded signal. | | | The basic physical operation of a hard disk drive is similar to that of a floppy disk drive: A hard drive uses spinning disks with heads that move over the disks and store data in tracks and sectors. |

| | What is disk drive? - A Word Definition From the Webopedia Computer Dictionary |
| | Disk drives can be either internal (housed within the computer) or external (housed in a separate box that connects to the computer). | | | A magnetic disk drive reads magnetic disks, and an optical drive reads optical disks. | | | For example, a hard disk drive (HDD) reads and writes hard disks, and a floppy drive (FDD) accesses floppy disks. |

| | What is disk? - A Word Definition From the Webopedia Computer Dictionary |
| | On magnetic disks, data is encoded as microscopic magnetized needles on the disk's surface. | | | Accessing data from a disk is not as fast as accessing data from main memory, but disks are much cheaper. | | | WORM disks can be written on once and then read any number of times; however, you need a special WORM disk drive to write data onto a WORM disk. |

| | Using disk drive motors |
| | ST506/412 hard disk interface is something like a modified floppy disk drive interface. | | | When you have just taken the motor out of the disk drive, you might have thought that there must be also a stepper controller inside the disk drive electronics. | | | The direction signals works so that low logic level moves the read/write head inward (towards the center of the disk) of the disk and high logic level moves the head outward. |

If I then change the floppy to any other one, it continues to see the first one... |

| | Floppy Disk Drive Primer |
| | Floppy disk drives were originally introduced commercially as a read-only device to hold microcode and diagnostics for large IBM mainframe computer systems in the early 1970s. | | | Often the drive's test points are difficult to locate, especially when the drive is installed in a computer, and of course using an AAD requires that one be well versed in the usage of an oscilloscope, etc. It is also very helpful to have some knowledge and experience maintaining diskette drives. | | | Knowing that their customers have computers with drives in various stages of misalignment, the software duplicator must make sure to place the software's data fields as perfectly as possible on the duplicated diskette. |

| | The main one is that if hard disk drive technology is to become the real replacement for tape storage - then cost per bit competitiveness - which some vendors claim has already been established - is not enough. | | | If you take the unit of a hard disk drive WORM repository as being a network connected RAID system rather than a single disk drive - then the problem with long term data viability is easily resolved. | | | WD was the only hard drive company amongst the top five vendors, which included Microsoft, Intel, HP and IBM. |
