MFM is modified frequency modulation and it works on floppy discs to encode the data. It is now becoming an obsolete system since DVDs and flash drives hold so much more data.
they are floppy disks
Depends on the floppy:Original IBM System/370 microcode 8 inch floppy - 80K bytesShugart OEM 8 inch floppy (single sided, FM recording) - 128K bytesShugart OEM 8 inch floppy (single sided, MFM recording) - 256K bytesShugart OEM 8 inch floppy (single sided, MFM recording, half width head) - 512K bytesShugart OEM 8 inch floppy (double sided, MFM recording, half width head) - 1M bytesShugart OEM 5 inch floppy (single sided, MFM recording) - 110K bytesApple ][ 5 inch floppy (single sided, GCR recording) - 140K bytesShugart OEM 5 inch floppy (double sided, MFM recording) - 220K bytesApple ][ 5 inch floppy (double sided, GCR recording) - 280K bytesIBM PC 3.5 inch floppy (MFM) - 720K bytesApple Macintosh 3.5 inch floppy (GCR) - 800K bytesIBM PC 3.5 inch floppy (HD MFM) - 1.44M bytesApple Macintosh 3.5 inch floppy (FDHD) - 1.6M bytesNote: many more floppy types and formats than are listed above are omitted because of limited usage or obscurity.
Floppy disks.
Most floppy disks will come pre-formatted. All floppy disks need to be formatted to be usable.
Four (4) startup disks are needed to boot Windows 2000 from floppy disks.
Floppy disk has tracks and sectors.
for putting floppy disks in it
hard disks are generally contains within the computer and contain FAR more memory than a floppy disk does. floppy disks generally contain 1.44 mb where as hard drives are constantly developing and are currently about 1TB MAX. floppy disks are external in the same way as CD's
You would need 729 floppy disks to hold 1GB of data. This is because:1 gigabyte is equal to 1,073,741,824 bytes1 floppy disk can hold 1,474,560 bytesSo floppy disks per gigabyte is equal to 1,073,741,824 divided by 1,474,560, which is 728.18 disks. This means you would need 729 disks to hold the full 1GB.
Yes.
No they are not
