Simple kuti kunzwisisa: chakaoma dhisiki mudziyo

Chimwe chikuru zvinoriumba chero kombiyuta ndiyo nemotokari rakaoma. mudziyo iyi aizivikanwawo pasi mazita jargon "sikuruu", "mutsvairo" zhestkach "," HDD "," zvakaoma ". The yokupedzisira chikwereti yakatangira kuna Chirungu zita - Hard Drive Disc (HDD), mu Russian colloquially kupfupiswa kuti "nesimba." Winchester rudzi mashoko kuchengetwa, asi mashoko iyo, kusiyana ndangariro zvabatwa kunyange kana simba akakundikana zvachose. Kusvika pamwero wakati, unogona kushumira somukuru analoginen yekare vhidhiyo uye makaseti matepi, umo rinobva firimu anoita basa rakafanana sezvo disks iri rakaoma Zvifambiso.

Hapana mubvunzo kuti vakawanda varidzi kombiyuta vangada kudzidza zvakaoma dhisiki mudziyo. Chii vanoridza mukati kana akatendeuka mberi, nei paine segwenhure ruzha apo zvinoshingaira iverengwe / kunyora ruzivo, uye zvichingodaro. Uye kana pane hwindo zvisingazivikanwi chinangwa. Pane mibvunzo yakawanda, asi zvakaoma dhisiki mudziyo uye anoramba ari chakavanzika.

Munyaya ino tinoda kujekesa zvimwe pfungwa dzinokosha. Kunze, zvichida, mumwe kuziva User uyo anosarudza kutanga pachake kugadzira zvakaoma ngarurege yavo disassembling zvakadaro, funga kagumi pamusoro feasibility iyi uye kutaura basa centre.

Zviitiko zvose zviripo Zvifambiso rakaoma yakagadzirwa nesimbi. Pamusoro underside of iripo bhodhi Electronics. Chip inogona soldered tiine kunze (womuenzaniso yekare), uye mukati. On chokupika isina kukanganiswa, kunze netsaona kurwadzisa yakabudikira Chip ane womukati urongwa hazviiti.

zvakaoma dhisiki mudziyo kunosanganisira achiisa pamusoro kadhi controller (MCU), ndangariro buffer Chip (yaizivikanwa DDR), kudzorwa module anoverenga (kurekodha) misoro - VCM, ROM kuyeuka kudzora firmware uye anodzivirira diode (TVs). The bhodhi chokuita dzakawanda zvinhu dzimba (containment) mhangura clamping vokukurukura.

Chokwadi, zvakaoma dhisiki mudziyo haagoni kunzwisiswa pasina kubvisa (chaiye kana nepfungwa) pamusoro pechifukidziro. Inside mumwe chete chokurukisa injini (kubvira 5.400 kusvika 15,000 nokumukirana paminiti, zvichienderana muenzaniso) akaisa maCD dzinoverengeka asiri conductive zvinhu. On pamusoro wavo zvemapuranga magnetizable rukoko: rangarira makaseti - hwaro polymeric tepi paiva. Mumwe Disc anoiswa rinokosha aerodynamic chinhu chakakombama akaita zvaida mhepo dziriko. Pamatanda, izvo akaisa panguva kumigumo musoro, iri kure mamiriro ndee rinokosha yokupakira motokari kunze Disc pemvura nomukombiyuta chihuri uye (kana) ari magineti. Mushure chokurukisa kusimudzirwa pave wokufema VCM kadhi inokinura pamatanda uye anoratidza nayo rwekuita chinzvimbo. Head panguva hamubati Disc pamusoro, uye kubhururuka pamusoro pavo pamusoro hovercraft. Panzira, kana iwe chokukuvadza kuti rotational simba kwakakwanira simba urwu uno yakakwana kuunza misoro iri yokupakira motokari (anenge 20-30 apfuura, zvakanga zvakafanira kuti nokuparura yakakwirira-pamwero kupaka chirongwa).

Saka, hapana Vacuum mukati zvakaoma nemotokari, uye "mahwindo" iri redzimba inodiwa equalize kufurirwa mukati nekunze. Chokwadi, mhepo mukati riri substantially isina guruva. Segwenhure vachishingaira kushandiswa zvakaoma dhisiki kunoitika nokuda kugara Positioning misoro kuti mugove akakumbira kuti denderedzwa (njanji). Eya, zvinyoronyoro tinya apo zvechizarira inogona kukonzerwa kubviswa yokupakira motokari kana kuti kuzvipira bvunzo nemiganhu.

Sezvineiwo, mashoko kwokunze zvakaoma dhisiki mudziyo uri zvakangofanana. Kunze: The kuwedzera kukurumbira muenzaniso pahwaro hwakasimba-hurumende ndangariro ushande mazano akasiyana zvachose.
