To read, there are very small electric coils that sense the magnetic polarization; these coils are mounted on arms which pivot and move across and very close to the surface of the disk.
(see the image link under Sources... below)
These coils read the polarization which represents the 1's and 0's of the binary information stored on the magnetic disk.
The write mechanisms make use of the electricity flowing through a coil in the write head that produces a magnetic field. Electrical pulses are sent to the write head, with different patterns of positive and negative currents. The current in the coil of the write head induces a magnetic field across the gap between the head and the magnetic disk platter, which in turn magnetizes a small area on the recording medium.
The Read/Write head assembly works to read and write using basically the same technology, early units used the same hardware for both, modern units can have slightly different configurations of the microscopic gaps between coils and magnets etc. for optimum performance.
collection of related data stored on a hard disk
Data can be stored on floppy disk, hard disk, memory stick, CD or DVD.
hard disk
Soft data is stored on a data disk or hard drive. Where as hard data is printed.
Are you asking "How is data/files" stored on a spinning magnetic disk within a hard drive, or are you asking how is data/files stored within the flash memory cells of a Solid State [hard] Drive (SSD)? Or, are you asking, "what is a hard disk drive" or "What is inside a hard drive?" Thanks!

Hard disk is recorded, main comes and goes.
Rom or secondary storage like the hard disk
The hard disk drive platter is used to store magnetic data or information that comes from the hard disk drive, where they are stored. The hard disk drive can contain one or more hard disk platter.
Yes, any data that can be stored on a hard drive can also be stored on a flash disk. A flash disk can even be configured with a boot sector and you can "boot" your computer from the flash disk.
As data in binary format of 0 & 1 on hard drive sectors.
A hard disk acts as a storage device for data. Data is also retrieved from the hard disk. The data that is kept in the hard disk is not erased even when the computer is switched off.
