Read/Write Heads
This is called "Formatting"
Reading a disk involves accessing and retrieving data that is already stored on the disk, while writing to a disk involves adding new data or modifying existing data on the disk. Reading does not change the content of the disk, whereas writing alters the information stored on the disk.
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.
A Disk
Its called a floppy disk.
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.
Yes
Floppy disks use magnetic disk to store the data.
A magnetic disk is a disk which stores information magnetically, and is read/written with a small magnetic head (e.g. a hard disk)An optical disk is a disk which stores information optically, usually as a series of pits and peaks, and is read/writMagnetic Storagea) Stores data in magnetic form & it doesn't use laser to read/write datab) It is affected by magnetic field.c) It has high storage capacity.d) Data accessing is high as compared to CD's and DVD's.e) Magnetic storage devices are ; Hard disk , Floppydisk, Magnetic tape etc.Optical Storagea) Stores data optically & uses laser to read/write.b) It is not affected by magnetic field.c) It has less storage than hard disk.d) Data accessing is high as compared to floppy.e) Optical storage devices are ; CD-ROM,CD-R,CD-RW, DVD etc.
surface of a disk to see if the sectors are capable of correctly reading and writing data
It's a track (a section of a magnetic disk, or a section of any given storage device that emulates a magnetic disk that uses the the LBA/CHS[Cylinder, Head, Sector]) that the computing device dedicates to store parity data (data to aid in error verification/correction for data that is stored on the disk).
A disk drive work in a rigid magnetic disk fixed permanent drive unit, and used for storing comuter data.
