Problems solved by technology

Only by increasing the number of magnetic heads, but without changing the way of reading and writing of mechanical hard disks, the speed of reading and writing cannot be effectively improved
[0007] In addition, due to the traditional Winchester hard disk structure, it is necessary to use a motor to drive the disk to read data, and the energy loss generated by this method is still very large
Moreover, the high-speed operation of the disk also brings hidden dangers to the stability of the mechanical hard disk and data security.

Embodiment 1

[0051] Figure 2(a) is a circular disk. The shape of the magnetic disk of the existing hard disk is mostly circular, and the magnetic track is a concentric circle structure. Round disks are well compatible with existing disks, reducing disk costs. The circular disk 11 is divided into a plurality of small fan-shaped sub-areas 111, 112...11n (n is a positive integer) according to concentric tracks, and each sub-area corresponds to a plurality of addressing units. The arrayed magnetic heads arranged on the circular magnetic disk 11 correspond to each sub-region one by one, and the arrayed magnetic heads are distributed concentrically from the center of the magnetic disk 11 along the radial direction. The distances between adjacent magnetic heads in the same radial direction are the same or different. When reading and writing, the magnetic disk 11 is fixed, and the piezoelectric ceramic material drives multiple magnetic heads to perform contact sliding addressing in their corresp...

Abstract

The invention provides a parallel contact read-write hard disk with an array magnetic head and a read-write method thereof. The hard disk includes a magnetic disk and an array magnetic head arranged on the magnetic disk, and a layer of super-slip material is attached to the surface of each magnetic head. The magnetic disk is divided into multiple sub-areas, each sub-area includes multiple addressing units, and each magnetic head corresponds to each sub-area one by one. When reading and writing, the magnetic disk is fixed, and the driving part arranged on each magnetic head controls the plurality of magnetic heads to slide in the corresponding sub-area simultaneously, so as to realize the simultaneous reading and writing of the plurality of magnetic heads. The hard disk changes the structure of the existing Winchester hard disk, avoids disk rotation, and multiple magnetic heads simultaneously read and write, thereby greatly increasing the reading and writing speed of the hard disk, reducing noise, and improving the life of the hard disk and data security.

Description

technical field [0001] The invention belongs to the field of storage devices, in particular to a contact-type read-write hard disk with parallel array magnetic heads. Background technique [0002] Nowadays, no matter in terms of read / write speed or storage density, the development of hard drives is facing a bottleneck. Solid-state drives are developing rapidly, and their reading and writing speeds are significantly higher than those of mechanical hard drives. However, their unit storage costs are too high, their security is insufficient, data is basically irreparable after damage, and their service life is short. These fatal flaws greatly restrict its development. [0003] The existing mainstream mechanical hard disk has obvious cost advantages, but the internal data transmission speed is generally between 20MB / s-40MB / s, and the highest is only about 50MB / s. That is, compared with solid-state drives, the read and write speeds of mechanical hard drives still need to be impro...
