What are the parts of diskette?

Answer 1

The Drive
The major parts of a FDD include:

• Read/Write Heads: Located on both sides of a diskette, they move together on the same assembly. The heads are not directly opposite each other in an effort to prevent interaction between write operations on each of the two media surfaces. The same head is used for reading and writing, while a second, wider head is used for erasing a track just prior to it being written. This allows the data to be written on a wider "clean slate," without interfering with the analog data on an adjacent track.
• Drive Motor: A very small spindle motor engages the metal hub at the center of the diskette, spinning it at either 300 or 360 rotations per minute (RPM).
• Stepper Motor: This motor makes a precise number of stepped revolutions to move the read/write head assembly to the proper track position. The read/write head assembly is fastened to the stepper motor shaft.
• Mechanical Frame: A system of levers that opens the little protective window on the diskette to allow the read/write heads to touch the dual-sided diskette media. An external button allows the diskette to be ejected, at which point the spring-loaded protective window on the diskette closes.
• Circuit Board: Contains all of the electronics to handle the data read from or written to the diskette. It also controls the stepper-motor control circuits used to move the read/write heads to each track, as well as the movement of the read/write heads toward the diskette surface.

Answer 2

Considering that you are speaking about a floppy disk the parts are as follows:

Here are all the parts of the disk that you can find if you look carefully:

• A metal shutter
• A spring
• A brown plastic circle from a metal center or hub (The circle is made out of the same stuff cassette tapes and videotapes are made of.)

• Two white paper rings
• A small black plastic rectangle with legs (Hint: it's up in one of the corners.)
• A small plastic flap
• Two plastic squares that hold everything else
