Abstract
An access method of memory hard disc which is different from the traditional reading and writting manner of the memory bodies uses a dual shaft servo driving unit to bear the photoreading-writting unit to make the photoreading-writting unit up and down, right and left servo-displacement round the periphery side of the fixed memory hard disc or in depth direction for reading and writting by the telescoping focus of laser beam or float head of reading and writting.
Description
The present invention relates to a kind of reading/writing method of memory hard disk, but particularly a kind of method and device of information of quick access high power capacity memory hard disk.
General rotary type disk drive system, for example hard disk drive system uses a magnetic head to read and write the magnetic information on the disk in the rotation.When disk drive system was closed, magnetic head then rested on the magnetic disk surface, or magnetic head regains from magnetic disk surface, to avoid injuring this disk.After aforementioned system is activated, hard disk rotates along its central shaft, and this magnetic head and disk keep in touch mutually, up to making magnetic head ＂ magnetic float ＂ (or flight) till the relative velocity above the disk, when the floating flight of this magnetic head magnetic is above the round rail of rotation hard disk, just can realize its read-write motion.
But in the general disc driver, this magnetic head has generally slided the hundreds of inches of this disk of contact before flight, can cause the excessive consume of magnetic head.
Secondly, general disc driver can make the disk in the rotation produce centrifugal action, cause magnetic head to move radially on the read-write spinning disk during information, just this disk drive head radially moves along this disk, one gets involved when rotating in order to the structure of ＂ flight ＂ disk drive head and this disk and produces between the direction of ＂ wind ＂ relative to distorting the angle, this distortion angle may cause the unnecessary shake of flying height and in order to the instability in the structure of ＂ flight ＂ disk drive head, this distorts the angle and also causes signal to the noise specific damping.
In addition, the actual magnetic segment length of general rotary type disk drive system changes with the function of this disk radius, the data quantity of the limited ability of its compression data in the fixed length segment that only can have a disk, just general rotary type disk drive, need the center of disk is installed on the central shaft, so circular magnetic disc can be for the surface area of record, reality only accounts for three/the last two of monoblock disk (when for example being the laser sheet, the chow ring frame of its centre perforation and confession grasping, neither can the use).
Hou, general disk are confirmed in read-write, servo writing with last settled, and all repeatedly are held its center, and this kind repeatedly clamped can cause disk to be distorted.
Therefore, first purpose of the present invention is to provide a kind of access method of memory hard disk, but the fast reading and writing memory hard disk.
Second purpose of the present invention is to provide a kind of access method and device of memory hard disk, can locate minimum read/write surface for read (or space) displacement up and down of motionless memory hard disk at this, and to memory hard disk be depth to carry out retractility light beam (or light velocity) access data.
