HDD, disiki ikomeye, Winchester - Aya mazina yose yigikoresho kimwe gizwi. Muri ibi bikoresho tuzakubwira kubyerekeye tekiniki ya disiki nkabo, uburyo amakuru ashobora kubikwa kubikwa, kandi andi mahame ya tekiniki n'amahame y'imikorere.
Igikoresho gikomeye cya disiki
Ukurikije izina ryuzuye ryiki gikoresho cyo kubika - disiki kuri disiki zikomeye za magneti (HMD) - Birashoboka kumva nta gikorwa cyinshi, zikoreshwa nakazi kayo. Ndashimira bihendutse no kuramba, ibi bitangazamakuru byashyizwe muri mudasobwa zitandukanye: PC, mudasobwa zigendanwa, seraves, ibinini, ibinini, nibindi. Ikintu cyihariye cya HDD nubushobozi bwo kubika amakuru menshi, mugihe kimwe mugihe kimwe. Hasi tuzavuga kubikoresho byayo byo murugo, amahame yakazi nibindi biranga. Barindi!Ikigo cya Hermobal na Electoronics
Icyatsi kibisi hamwe na trapper kuriyo, hamwe no guhuza kugirango uhuze amashanyarazi na Soke ya Sata Kwishura Umugenzuzi wumuzunguruko, PCB). Uyu muzengurutswe ukoreshwa muguhuza imikorere ya disiki muri PC hamwe nigitabo cyibikorwa byose imbere muri HDD. Amazu yumukara aluminium nibiki imbere byitwa Bifunze (Umutwe n'inteko ya disiki, HDA).
Hagati yumuriro uhujwe hari chip nini - ni Microcontroller (Micro Ingenzura Igice, MCU). Muri HDD yiki gihe, microProcesor ikubiyemo ibice bibiri ubwabyo: Guhagarika hagati (Igice cyo gutunganya hagati, CPU), bikora imirimo yose, kandi Umuyoboro usoma no kwandika - Igikoresho cyihariye gisobanura ibimenyetso bivuye mumutwe muburyo butandukanye iyo bihuze gusoma no kubiba - Disita - Digital muri Analoge mugihe cyo gufata amajwi. MicroProcessor ifite I / O PORTS Hamwe nubufasha bugenzura ibintu bisigaye biri ku kibaho, kandi bigatuma amakuru agenga amakuru akoresheje sata.
Indi chip iherereye ku gishushanyo ni ddr sdram ibuye (chip yibuka). Umubare wacyo wahanuwe ingano ya kesh Winchester. Iyi chip igabanijwemo ububiko bwa software, ikubiye igice muri Flash Drive, na buffer, itunganya ikenewe kugirango ushyire software software.
Chip ya gatatu yitwa Moteri n'umutwe (Ijwi rya moteri ya moteri ya moto, umuyobozi wa VCM). Igenzura isoko ryinyamanswa ziherereye ku buyobozi. Bakira ibiryo bya microprocessos kandi Guhinduranya Preamplifier) bikubiye mu kaga gafunze. Uyu mugenzuzi asaba imbaraga zirenze izindi ngingo zigize Inama, nkuko bikwiye kuzunguruka spindle no kugenda k'umutwe. Intangiriro yo guhinduranya ibibanza ishoboye gukora, gushyuha kugeza 100 ° C! Iyo imbaraga zitangwa kuri HDD, Microcontroller ipakurura ibiri muri flash chip murwibutso hanyuma itangira ishyirwa mu bikorwa ryamabwiriza yashyizwemo. Niba code idashobora guterwa neza, HDD itazatangira kuzamurwa mu ntera. Ububiko bwa flash burashobora kubakwa muri microcontroller, kandi ntabwo ikubiyemo Inama y'Ubutegetsi.
Giherereye kuri gahunda Vibration Sensor (Ssubiness Ssersor) igena urwego rwumurongo. Niba ireba ubukana bwayo ari bibi, noneho ikimenyetso cyoherezwa umugenzuzi wumugenzuzi wa moteri numutwe, hanyuma bihita bihita bihindura imitwe cyangwa bihagarika kuzunguruka HDD. Mu nyigisho, ubu buryo bugamije kurinda uburinzi bwa HDD kwangirika nabi, ariko, mubyito mubikorwa ntibimuka byinshi. Kubwibyo, ntabwo bikwiye guta disiki ikomeye, kuko irashobora gusaba akazi kadahagije vibrator, ishobora gutera umuntu wuzuye ibikoresho. Bamwe mu njmds bafite ubwitonzi buhebuje kunyeganyega na sensor bakira ibintu bito. Amakuru vcm yakira afashwa muguhindura urujya n'uruza rw'imitwe, bityo discs ifite byibuze sensor ebyiri.
Ikindi gikoresho cyaremewe kurinda HDD - Inzibacyuho Voltage ntarengwa Imyambarire ya voltage, TVS), yagenewe gukumira kunanirwa kunanirwa mugihe cya voltage gusimbuka. Igishushanyo kimwe cyuko abo bagarukiye barashobora kuba bwinshi.
Ubuso bwa germoblock
Munsi yamafaranga ahuriweho harimo guhuza moteri n'umutwe. Ako kanya urashobora kubona umwobo wa tekiniki utagaragara (umwobo uhumeka), uhuza igitutu imbere ndetse no hanze yakarere ka kashe kangiza umugani uri muri disiki ikomeye. Agace k'imbere karimo akayunguruzo kadasanzwe katabura umukungugu nubushuhe muri HDD.
Imbere ya Shomblock
Munsi yumupfundikizo wumuriro, nicyo kigega gisanzwe cyicyuma hamwe na gabe ya rubber irinda ubuhehere n'umukungugu, ni magnetiki.
Barashobora kandi kwitwa Pancake cyangwa Amasahani (Platters). Disiki isanzwe iremwa kuva mu kirahure cyangwa aluminium, yabayeho mbere. Noneho bitwikiriwe nibice byinshi byibintu bitandukanye, harimo na FerromaGNES - Murakoze kuri we kandi birashoboka kwandika no kubika amakuru kuri disiki ikomeye. Hagati yisahani no hejuru ya pancake yimbere iherereye abagabana (Abamugaye cyangwa abatandukanya). Bahuza umwuka ugenda kandi bagabanye urusaku rwa acoustic. Mubisanzwe bikozwe muri plastiki cyangwa aluminium.
Isahani yo gutandukanya yakozwe muri aluminiyumu nibyiza guhangana no kugabanuka kwubushyuhe bwikirere imbere muri zone ya Hermetic.
Guhagarika imitwe ya magnetic
Ku mpande zose ziherereye Guhagarika umutwe (Inteko ikora umutwe, HSA), gusoma / kwandika imitwe. Iyo spindle ihagaritswe, igomba kuba mukarere ka PRTR - Aha ni ahantu imitwe ya disiki nziza iherereye mugihe igiti kitakora. Muri parikingi ya HDD ibera ku banga ba plastike, iherereye hanze y'isahani.
Kubikorwa bisanzwe bya disiki ikomeye, nkumwuka mwiza urakenewe, urimo byibuze ibice bya gatatu. Igihe ntarengwa, micropartarticle ya lubricant nicyuma gishyirwaho muri compumulator. Kugaragara, HDD ifite ibikoresho Kuyungurura . Bashyizwe munzira yo kuzenguruka, zakozwe bitewe no guhinduranya amasahani.
Igishushanyo cya Neodymium, gishobora gukurura no gufata uburemere, bushobora kuba inshuro zirenga 1300, zashyizwe muri NJD. Intego yiyi magnets muri HDD ni ukubuza kugenda kwumutwe ubifashe hejuru ya plastike cyangwa aluminiyumu pancake.
Ikindi gice cyumutwe wa rugnetic ni coil (Coil). Hamwe na magnets itunganijwe Gutwara Bmg hamwe na bmg ni Positioner (Actuator) - Igikoresho cyimuka. Uburyo bwo kurinda iki gikoresho bwitwa kugumana (Actuator Latch). Birekuye bmg vuba aha spindle yunguka umubare wa revolion. Muburyo bwo kwibohora, igitutu cyurugendo kirimo. Igishushanyo kibuza ingendo zose z'umutwe muri leta yo gutegura.
Munsi ya BMG izaba ifite intego. Ishyigikira ubwonko no muriki gice. Ako kanya igice gikozwe muri aluminium alloy, kitwa Koromysl (Ukuboko). Ku iherezo ryayo, ku nkombe y'impeshyi, imitwe iherereye. Kuva kuri rocker ni Umugozi woroshye (Umuzunguruko woroshye wacapwe, FPC), biganisha kuri padi, bihujwe ninama ya elegitoroniki.
Ibi nibyo coil isa, bifitanye isano numugozi:
Hano urashobora kubona kubyara:
Dore imibonano ya BMG:
padi (Gasket) ifasha kwemeza neza. Bitewe nibi, ikirere kigwa muri clok hamwe na disiki nimitwe gusa binyuze mumuyaga uhuza igitutu. Ihuza ryiyi disiki ritwikiriwe nubuzima bwiza, butera imbaraga.
Iteraniro risanzwe ryiteka:
Kurangiza ihagarikwa ryimpeshyi hariho ibice bito - Ibibanza (Slide). Bafasha gusoma no kwandika amakuru mukuzamura umutwe hejuru yisahani. Muri drives zigezweho, imitwe ikora, iherereye kure ya 5-10 nm kuva hejuru yibyuma. Ibintu byo gusoma no kwandika biherereye kumpande zose za slide. Ni nto cyane kuburyo bashobora gukoreshwa gusa na microscope.
Ibi bice ntabwo ari igorofa rwose, kubera ko hari ibiryo bya Aerodynamic bikora kugirango bihatize uburebure bwindege. Umwuka munsi yirema Umusego (Ikirere kirimo ikirere, ab), gishyigikira hejuru yindege.
PREAMP - Chip ishinzwe kuyobora imitwe no kukwaza ikimenyetso kuri bo cyangwa kuri bo. Iherereye muri BMG, kuko ikimenyetso cyerekana ko imitwe itanga, ifite imbaraga zidahagije (hafi 1 ghz). Hatariho amplifier muri zone yumujitsi, yaba yaratatanye gusa munzira igana kuzunguruka.
Kuva kuri iki gikoresho ugana kumitwe Hariho inzira nyinshi zirenze zonko ya Hermetic. Ibi birasobanurwa nukuri ko disiki ikomeye ishobora gusabana numuntu runaka mugihe runaka mugihe. Microprocessor yohereza ibyifuzo kumunwa kugirango ahitemo umutwe ukeneye. Kuva kuri disiki kuri buriwese hari inzira nyinshi. Bashinzwe gucengera, gusoma no kwandika, gucunga ibinyabiziga miniture, bakorana nibikoresho byihariye bya rukuruzi, bishobora kugenzura slide, yemerera kongera imitwe. Umwe muribo agomba kuganisha ku cyumba cyuma gihindura uburebure bwo guhunga kwabo. Iyi mikorere ikora nkibi: ubushyuhe bwandurwa mubushyuhe, buhuza slide na rocker. Ihagarikwa ryakozwe kuva iLory ifite ibipimo bitandukanye byo kwagura mubushyuhe bwinjira. Hamwe n'ubushyuhe bwongera, bwunamye ku isahani, bityo bigabanya intera kuva kumutwe. Hamwe no kugabanuka k'ubushyuhe, ibikorwa bitandukanye bibaho - umutwe ukurwaho na panda.
Iyi nzira isa nkumutandukanya hejuru:
Iyi foto irimo akarere keza hatabayeho guhagarika imitwe na ba disani yo hejuru. Urashobora kandi kubona magnet yo hepfo kandi impeta ya clamping (Amashurwe):
