Description

A kind of super hard disk of high capacity drum type brake magnetic drum

Technical field

The utility model belongs to seagate field, and in particular to a kind of super hard disk of high capacity drum type brake magnetic drum.

Background technique

Hard disk is one of main storaging medium of computer, is made of the disk of one or more aluminum or glass system, Ferrimagnet is covered with outside disk.

Hard disk has solid state hard disk (SSD disk, modern hard disk), mechanical hard disk (HDD conventional hard), (mono- piece of HHD of hybrid hard disk The new hard disk for being born out based on traditional mechanical hard disk).SSD is stored using flash memory particle, and HDD is deposited using magnetic disk Storage, hybrid hard disk is a kind of hard disk that magnetic hard-disk and flash memory are integrated together.Most hard disks are all Fixed disk, quilt Permanently sealing is fixed in hard disk drive.Multihead technology: by increase on same disk multiple magnetic heads simultaneously It reads or writes and raises speed for hard disk, or read or write simultaneously using magnetic head simultaneously in DVD multidisc piece to raise speed for disk, be chiefly used in servicing Device and database hub.

Caching is one piece of memory chip on hard disk controller, has the access speed being exceedingly fast, it is hard drive internal storage Buffer between extraneous interface, since the internal data transfer speed of hard disk is different with extraneous interface transmission speed, caching Wherein playing the role of a buffering, the size of caching and speed be directly related to hard disk transmission speed it is important because Hard disk overall performance can be significantly increased in element.Mean access time refers to magnetic head from initial position to arrival goal track Position, and time needed for finding the data sector to be read and write from goal track, mean access time embody hard disk Read or write speed, it includes the tracking time and waiting time of hard disk, it may be assumed that mean access time=average seek time+average Waiting time.The average seek time of hard disk refers to the time needed for the magnetic head of hard disk is moved to disk specific track；Hard disk Waiting time is called incubation period, refers to that magnetic head has been in the magnetic track to be accessed, the sector to be accessed is waited to rotate to magnetic head The time of side.Revolving speed is the rotation speed of electric machine main shaft in hard disk, that is, hard disc can be done most in one minute Big revolution, it is one of the key factor for determining hard drive internal transmission rate.As the data storage of computer system, capacity is The most important parameter of hard disk.

Present supercomputer is usually the computer system being made of multiple computer nodes, its hard-disk system is also Special disc array system, the hard disk quantity used is very big, up to 5000-10000 muti-piece common hard disc, and communication is generally used up Fibre, memory then distribute the quantity in each calculate node and are difficult to calculate, the smallest memory for obtaining 1TB or more, current maximum list Block hard-disk capacity has 2TB, if pressing the calculation of capacity of external memory 12.4PB used in No. two supercomputers of the Milky Way, 2TB 5000 muti-pieces of monolithic hard disk, 5000 muti-piece hard disks and hard disk array control equipment power consumption it is big.

The existing super hard disk of high capacity drum type brake magnetic drum, there is also the deficiencies of following aspect when in use:

1. plug, there is dust entrance, is unfavorable for increasing the protection to plug outside being exposed to；

2. shell is outer due to lacking protection, aggravates the load of super hard disk when shell is fallen, reduce super hard disk Service life.

Utility model content
