2. The floppy disk drive was invented by Alan
Shugart in 1967.
The first floppy drives used an 8 inch disk
which evolved into the 5.25-inch disk that
was used 1981
The 5.25-inch disks held 360 kilobytes
3. The floppy disk is like a cassette tape
It has a thin plastic base and a material
coated with iron oxide
The iron oxide is a ferromagnetic material
that if it is exposed to a magnetic field it is
permanently be magnetized by the field
It records information instantly, be erased
and reused many times and is inexpensive
and easy to use
5. 8-5
High capacity
Known as a floppy-disk cartridge
Require special disk drives
Three well known types
Zip disks (Iomega)
100MB, 250MB, 750MB
HiFD disks (Sony)
200MB, 720MB, read and store data on 1.44MB disk
SuperDisks (Imation)
240MB, 120MB
7. Since technology has evolved floppy disks
drives are no longer being installed in
computers
Many people still prefer floppy disks and they
are able to use it by attaching a USB floppy
drive
The drive can be attached to any computer
The drive will cost you about $20
8. 1. Remove second slide panel from case.
2. Remove the face plate and insert drive into
floppy bay.
3. Screw in the floppy drive.
4. Locate floppy disc drive cable.
5. Hook it up to the motherboard.
6. Adding power.
9. Since technology has evolved floppy disks
have been hard to find
It has been replaced by USB sticks which are
more convenient and more durable
USB sticks will cost about $10-$35 depending
on the storage amount
10. 1. What year was the first 5.25-inch floppy disk
used?
2. What is no longer being installed in computers?
3. What is the name of the drive that can be
attached to any computer?
4. What have floppy disks been replaced with?
5. Give at least one type of floppy disc and
describe
6. Summarize the proper installation procedure
on installing the floppy disk drive.(5 pts.)

Storage capacities range from 360 KB to 1.44 MB Write-protect notch or window to prevent inadvertent erasure or write-over Density refers to how tightly the bits can be packed next to one another A shutter on the disk slides to the side to expose the recording surface
Zip disks – usually manufactured by Iomega; 100 to 250 MB worth of storage; requires own drive Super disks – usually manufactured by Imation; 120 MB capacity; popular with notebooks; use std floppy drive HiDF disks – usually manufactured by Sony Corp; 200 MB capacity Biggest advantages: can use HiDF disk in floppy drive Zip disks – 100 MB, 250 MB or 750 MB HiFD disks - 200MB or 720MB SuperDisks – 120 MB or 240 MB
