Reading from and writing to a disk surface typically does not occur due to the use of non-contact technologies like magnetoresistive heads in hard disk drives (HDDs) or laser technology in solid-state drives (SSDs). These technologies create a gap between the read/write head and the disk surface, allowing data to be accessed without physical contact, which reduces wear and tear. This non-contact method enhances durability and performance, minimizing the risk of damage to the disk surface.
no, the head not touching the surface of the hard disk. If it touch the great chance of data may be lost. only the head of floppy disk is touch the surface of the disk.

touch
In a hard disk the heads fly above the surface on a thin cushion of air, to prevent wear to the disk or heads. Should something cause the heads to touch the moving disk surface it is called a "head crash" and is not all that different from an airplane crash, as the heads quit flying on their cushion of air.
HDI - Head to Disk Interference.
A read/write ____ is the mechanism that reads and writes items in the drive as it barely touches the disk's recording surface
The disk is hardware, but information ON the disk is software. Rule of thumb is if you can touch it with your fingers, it is hardware. You can touch the disk, but you cannot touch files or programs.
read/write head
A hard disk is the physical medium information storage device of most computerized systems. It is an actual disk that rotates at high speed. The surface is coated with magnetic material, and data is stored magnetically on the surface. A tiny read/write head on the end of an arm that can move over the surface of the disk does the reading and writing to transfer the information to and from the medium.
In a magnetic disk drive, the special device that reads and writes data to the disk's surface is called a read/write head. This head operates at a very small distance from the disk platter, utilizing magnetic fields to detect and alter the magnetic orientation of the disk surface, thereby enabling data retrieval and storage.
In a magnetic disk drive, a special device called a read/write head is used to read data from and write data to the magnetic disk. The head floats just above the surface of the spinning disk, allowing it to access the magnetic fields that represent stored data. As the disk rotates, the head moves across the surface to locate the appropriate data tracks, enabling fast access to information.
In magnetic particles on the hard drive disk surface. The drive head reads the magnetic particles and interprets if they are ones or zeros. The head doesn't touch the disk surface but resides about .00005 thousands away from the surface. Just opening the drive housing in an unclean environment can render the drive unusable. It also voids the warranty
