Storage Medium for 4k

For some time, I have been watching a YouTube channel that displays old audio and video equipment. Watching the progress of storage medium is very interesting. At the moment the highest capacity storage medium is 100 GB with a triple-layer UltraHD Blu-ray disk. I would like to propose an alternative to that. A 120 mm floppy disk with a hard disk drive platter inside.

As solid state storage became the standard for computing, the demand for mechanical hard disk drives is diminishing. The know how developed on these magnetic disk drives can be transferred to come up with an alternative to optical counterparts. The mechanical disk drives have a higher storage density then their optical counterparts. They are also more reliable in the long run especially compared to multi layered disks. They would be somewhat more expensive though.

The trend with video is online. However, very high bit rate quality video and audio cannot be streamed over internet to many locations around the world. There would be still need for a read only medium to distribute very high-quality movies. Buying a very big and expensive TV and consuming highly compressed and lower quality media over internet can raise demand for such new medium. An enclosed hard disk drive platter can be an alternative to Blu-ray disks while they would allow much higher capacities and retain info more reliably.
