That's called a headcrash. Usually, the head and platters never touch, because the platters spin fast enough to generate an "air cushion" on which the head glides around.
HDI - Head to Disk Interference.
When a read/write head touches the surface of a platter, it can cause a phenomenon known as a "head crash." This occurs when the head makes contact with the spinning platter, potentially leading to physical damage of the magnetic surface and loss of data. Such contact can result in scratches or other forms of damage that compromise the integrity of the hard drive, often leading to data recovery challenges. Preventive measures, like proper handling and maintenance, are crucial to avoid head crashes.

Each side, or surface, of one hard drive platter is called a head. Windows Vista technology that supports a hybrid drive is called ready drive.
The concentric magnetic circles that run around a disk platter are called "tracks." Each track is a circular path on the surface of the disk where data is recorded. Data is organized in these tracks, and the read/write head of the disk accesses the information by moving to the appropriate track.
A head crash is a type of hard disk failure that occurs when a read/write head touches the fast spinning disk platters. It is very catastrophic - it can destroy lots of data - even the data needed to start an operating system can be destroyed.
