3.5 inch floppy drive is the place where you out the cute little disk. :)

1. When a disk is inserted the metal cover is pushed open to show the inside called the

cookie. The disk is coated with a magnetic material.

2. The two read/write heads one on the top and one on the bottom are very close to the

disk and send magnetic pulses that change the polarity of the particles on the disk when

writing.

3. The drive's circuit board gets signals from the computer and sends them to the head as

signals that control the heads movement. Meanwhile a motor attaches itself to the middle of

the disk and spins it. Another motor called a stepper motor turns moves the head back and

forth over the disk.

4. On a disk there is a little tab that determines whether you write to the disk, if the tab is

pushed up the disk will not write if it is down it will write to the disk. The drive

determines if it can write to the disk by shining a little light through the hole, if it senses the

light it will not write to the disk, if it does not sense the light it will allow you to write on

the disk.

5. The heads make electrical impulses that magnetizes the head and allows it to write data to

the disk. To read the data the head sense the magnetic fields made by the magnetic particles

in the cookie.
