The invention provides a high-performance reliable solid-state disk realizing method. The method includes: (1), dividing all flash memory chips in a solid-state disk into groups and forming an RAID (redundant array of independent disks) 4-level flash array in each group by N successive flash chips; (2), receiving and storing data through a cache; (3), judging whether the cache is filled up or not, if yes, entering the step (4), and if not, returning to the step (2); (4), extracting N-1 data blocks from the cache and computing check values of the N-1 data blocks; making up the N-1 data blocks and the check values into filled stripe data and writing back the flash array; returning to the step (2). The flash chips in the solid-state disk are used for establishing the RAID4-level physical array to assure data reliability. Faults at different levels including page level, block level, or even chip level can be processed. Besides, writing-in performance is improved by writing of filled stripes and sequence, and spatial and performance loss resulted from data errors can be reduced to the utmost.

An improved magnetic head comprises a slider and a thin film element, the later of which is provided on a trailing side of the slider. The slider has core layers. The surfaces of the core layers are abraded so that the thickness of an a phase constituting the surface structures of the core layers may be reduced to a very small value. In this way, even if a carbon film is directly formed on the core layers, it is still possible to ensure a desired diffusion between the carbon film and the a phase, thereby effectively preventing the carbon film from separation (peeling) and avoiding the formation of any spot on the carbon film.
