Digital information is stored in microscopic needles as part of the disk's magnetic coating.
Information is stored in the computer's hard drive, which is a magnetic disk read by lasers.
Yes. As magnetized north or south binary bits.
In a way, yes. The material that makes up the "disk" in a floppy is Mylar, a magnetic substance. Data is stored on the Mylar disk in the form of magnetic charges.
Widely used Magnetic platters Hard disk drives uses Properties of Magnetism. As known Data is stored in Binary form, the disk uses North/South Polarity created on Magnetic disk platter as 0 or 1 (binary digits). The sensor (Read/Write Head) in Hard disk senses magnetic orientation at a very small area and interprets it as Binary Digit.For storing data on Hard disk the magnetic orientations are changed according to data by Read/Write Head.
This sounds like a test question. This is not a good way to get an answer.
The harddrive stores data on a single magnetic disk, somewhat compareable to a CD in the way that it spins, its round, and it stores data. The "head" of the harddrive uses magnetic fields to excite different areas of the disk to store a binary code such as "00100010." Millions upon billions of these codes are stored on the disk with each code being a single command.
As data in binary format of 0 & 1 on hard drive sectors.
Yes, there are some surprisingly strong magnets in the Hard Disk Drive. The read/write "head" also is an electromagnet, and the "platter" (spinning disk) is magnetized, but over all not very magnetic.
A hard disk drive records data by magnetizing a thin film of ferromagnetic material on a disk. Sequential changes in the direction of magnetization represent binary data bits. The data is read from the disk by detecting the transitions in magnetization. User data is encoded using an encoding scheme, such as run-length limitedencoding, which determines how the data is represented by the magnetic transitions.
It is stored as magnetic impulses, similar to how a tape recorder records, except that the data is digital rather than analog.
Common hard disks with read/write heads are magnetic storage. The newer SSD (solid state drive) hard disks are not magnetic because there are no read/write heads. Solid state means no moving parts. SSD drives are labeled as such so you know what you are buying.
