The magnetic recording technique used for storing data onto the disks (floppy disks) is called
A. return to zero
B. non-return to zero
C. return to zero and Non-return to zero
D. none of the mentioned
Answer:A
The magnetic recording technique used for storing data onto the disks (floppy disks) is called
A. return to zero B. non-return to zero C. return to zero and Non-return to zero D. none of the mentioned
