Sahlan ee kakan: qalab disk adag

Mid ka mid ah qaybaha ugu muhiimsan ee kombiyuutar kasta waa drive adag. qalab Tani waxaa sidoo kale loo yaqaan hoos erey magacyada "fur", "rotem" zhestkach "," HDD "," adag ". Arintaan ku leedahay asal ahaan ay u magac Ingiriisi ah - Hard Drive cajalid (HDD), ee Ruush colloquially gaabisay inay "adag tahay." Winchester waa nooc ka mid ah oo macluumaadka lagu kaydiyo, xogta, taas oo, ka duwan xasuusta ceshan yihiin xataa haddii awood buuxda u guuldareysto. Ilaa xad gaar ah, uma shaqayn karo sidii analog ah ee video iyo maqal ah cajalado jir, taas oo filimka magnetic qabata shaqo la mid ah sida saxannada ee drives adag.

Ma jiro shaki in milkiilayaasha badan computer jeclaan lahaa in ay bartaan qalabka disk adag. Waa maxay gudaha baddhamada soo noqdeen on, sababta waxaa heesaha dhawaaqa marka akhrin firfircoon / qor macluumaadka, iyo wixii la mid ah. Oo kiiska jiro suuqa kala ah ujeedada aan la garanayn. Waxaa jira su'aalo badan, laakiin qalabka adag disk iyo weli wax qarsoon.

In this article waxaan rabnaa in aan iftiin ku daatay oo qaar ka mid ah qodobada ugu muhiimsan. Ka sokow, laga yaabee, user a cajiib ah kaasoo uu go'aansado inuu ku soo bilowdo dayactir iyaga u gaar ah drive adag la disassembling kiiska, qabaa toban jeer ku saabsan Bulshda ee this iyo la xiriir xarunta adeega.

Kiisaska oo dhan drives adag ee hadda jira waxaa lagu sameeyey bir. On underside ee ugu korantada guddiga la heli karo. Chip la soldered karaa iyadoo labada baxsan (model jir), iyo gudaha. On waxqabadka kama beddelayso, marka laga reebo by shil yeeli ridday chip la heshiis ah gudaha wax aan macquul aheyn.

qalab disk adag ku lug geliya on xakamaysada kaarka (MCU), xusuusta chip kayd (DDR la yaqaan), module gacanta ku akhriya ah (wax lagu qoro) madaxdii - VCM, xusuusta ROM firmware gacanta iyo diode difaac (telefishinada). Guddiga ayaa ku xiran yahay waxyaalaha gudaha oo ah naxaas ku tirtirayaan guryaha (xasilin) xiriirrada.

Dabcan, qalabka disk adag oo aan la fahmi karaa oo aan ka saareen ah (dhab ah ama maskaxda) cover sare. Inside on hal motor dunmiiqa ah (ka 5,400 ilaa 15,000 Kacdoonkii halkii daqiiqo, taas oo ku xidhan model ah) kaalinta dhowr CDs ka wax a non-tabinta. On ay dusha dahaarka leh lakabka magnetizable, oo bal xusuuso cajalado - saleysan cajalad polymeric waxaa jiray. disc kasta waxaa la dhigayaa arc gaar ah aerodynamic la xirrira socodka hawada loo baahan yahay. jir ah, oo waxaa la geeyaa at darafyadiisa oo madaxa, ee gobolka off fadhiya meel baabuurta la dhigto oo gaar ah oo ka baxsan dusha disc ah via soo dusiyey iyo (ama) ee magnetka. Ka dib kor u qaadida dunmiiqa abuuraa card VCM hawada u furayaa jir ah oo u soo bandhigay in booska shaqada. Head waqti isku mid ma taabto dusha disc ah, iyo duuli iyaga u taliya on the hovercraft. By habka, haddii aad gab tamarta wareeg ku filan dhalin xoog hadda ku filan in la keeno madaxdii goobta la dhigto (oo ku saabsan 20-30 sano ka hor, waxaa lagama maarmaan ahayd in aan bilowno barnaamij heer sare ah oo la dhigto a).

Sidaas darteed, waxaa jira vacuum ma drive adag gudahood, iyo "daaqadaha" ee guryaha ayaa loo baahan yahay si loola simo cadaadiska gudaha iyo dibadda. Dabcan, hawada gudaha waa ku ool ah free of ciidda. Heesaha isticmaalka disk adag firfircoon dhacaa sabab u tahay madaxdii boos joogto ah si ay qayb doonayo ee disk ah (track). Well, jilicsan a riix marka qufulka waxaa keeni kara ka saarida ee goobta la dhigto ama xadka is-imtixaanka.

Waana mid ka, qalab disk adag dibadda dhab ahaan waa isku mid. Marka laga reebo: model The sii kordheysa oo caan ku saleysan xasuusta adag gobolka ka shaqeeyaan mabaadi'da gabi ahaanba ka duwan.
