Hard Drive Technology Improvements

These technological improvements pertain to hard drive technologies that include hard disk platters. For an instance, there could be a hard drive that has NVRAM for storing the file system parameters, to make looking up the file system faster, and accessing the parameters of where the files are located on the disk much faster as well, in memory that doesn’t lose its states whenever the power is cut. Additionally, there could be hard drives that have additional NVRAM for commonly accessed files on the disks, such as Operating System files, and then files that are not accessed commonly or all the time could be stored on the hard disk platters. There could be a new type of read/write head for hard drives, that includes a piece of plastic, to avoid scratches to the hard drive platters, and also there could be more than one read/write location accessed, with additional writing on the piece of plastic to include many different tiny electromagnets, to allow accessing hundreds of different locations around the read/write head, for example, to also be able to verify that the correct locations are being accessed, by verifying that the information is accurate with special codes that are in platter sectors or segments, or even with some type of calculation that is stored by adding up all of the values and converting it to a CRC code for any given x,y,z location on the platters, with z being which platter it is on. Also, there could be a technology that stores hundreds, thousands, or even millions of different layers of magnetic stores on the platters, with special technologies that can precisely record and recall different values at different locations around the hard drives.
