In computing, double density is a term used to describe various methods of storing more than the usual amount of data on a given storage medium. The term is most often used in reference to floppy disks, which typically have a capacity of 1.44 megabytes. Some floppy disk drives are capable of storing 2 MB on a single floppy disk by using a technique known as “double density”.
The capacity of a floppy disk is determined by the number of tracks and sectors per track. A “double density” floppy disk has twice as many tracks as a standard floppy disk, and each track is divided into twice as many sectors. This allows for a total capacity of 2 MB.
There are a few different ways to achieve double density on a floppy disk. One method is to physically increase the number of tracks on the disk. This can be done by using a different type of floppy disk that has more tracks, or by modifying the floppy disk drive to store more tracks.
Double density is important for disk drives because it allows for more data to be stored on a single disk. This is especially important for large disk drives, where space is at a premium. Double density also allows for faster data transfer rates, which is important for applications that require high bandwidth.
The article discusses the concept of double density as it pertains to disks. Double density refers to the fact that a disk can store twice as much data in the same amount of space as a single density disk. This is because the tracks on a double density disk are twice as wide as those on a single density disk. Double density disks are able to store more data because they have more tracks per inch than single density disks. This means that double density disks can store more data in the same amount of space as a single density disk.
