Carbon nanotubes sun sami wani aikace-aikace. Kwanaki kadan da suka gabata, an buga wata kasida a mujallar Nature Scientific Reports cewa a karon farko an yi la'akari da yiwuwar amfani da Multiwall carbon nanotubes (MWCNT) a cikin rikodin maganadisu akan rumbun kwamfyuta. Waɗannan su ne nau'ikan tsarin CNT masu rikitarwa a cikin nau'ikan "tsananan matryoshka", "convolutions" da sauran tsarin. Aiki a duk lokuta ya zo zuwa abu daya - don cusa kowane irin hadadden carbon nanotube tare da Magnetic nanoparticles. Kowane Magnetic nanoparticle daban ba zai haifar da tasirin rikodin bayanai ba. Kuna iya canza magnetization na duka bututu kawai, amma har yanzu zai zama mai yawa fiye da rubuta yankin maganadisu akan farantin magnetic HDD na yau da kullun. Mafi yawa.
Masana kimiyya daga Jami'ar Alaska (Fairbanks) ne suka gudanar da binciken rikodin maganadisu akan MWCNT da sauran cibiyoyin kimiyya da yawa a cikin Amurka da Jamhuriyar Czech. Ɗaya daga cikin jagororin aikin shine masanin kimiyyar Czech Gunther Kletetschka. Kwararren ya lura cewa hanyoyin da ake da su don haɓaka yawan rikodi akan faifan Magnetic HDD ba su dace da saurin haɓakar bayanai ba. Don hana haɓakar bayanai, yawan ajiyar rumbun kwamfyuta yana buƙatar haɓaka da kashi 40% kowace shekara, kuma a cikin 'yan shekarun nan yana haɓaka da 10-15% kowace shekara. Rikodi ta amfani da bututun maganadisu na carbon na iya zama amsar ƙalubalen shekarun bayanai, amma babban aikin bincike ya rage a yi don wannan.
Asalin binciken shine cewa carbon nanotubes tare da nanoparticles na maganadisu a ciki an fallasa su zuwa filayen lantarki na amplitudes daban-daban da mitoci daban-daban. Af, samar da carbon tube cushe da nanoparticles da aka gudanar ta yin amfani da jita-jita a cikin wani gas yanayi - ba sabon abu. Lokacin da aka yi amfani da filin maganadisu tare da mitar har zuwa 10 kHz, babu abin da ya faru (sakamakon yanayin tafiyar da carbon nanotubes ya shafi), amma tare da karuwa a mita sama da 10 kHz kuma tare da raguwa a cikin girman filin, sakamakon. na magnetization na wani carbon nanotube tare da Magnetic nanoparticles ya tashi. A cewar masana kimiyya, filin waje ya zo cikin yarjejeniya da filin maganadisu na kowane barbashi, wanda ya ba da damar ba da nanotube barga magnetization a cikin wani shugabanci.
Masana kimiyya har yanzu ba su da shawarwari kan yadda za a ƙirƙira hanyoyin yin rikodi da karantawa don yin rikodin bayanai a kan tarin carbon nanotubes, amma sun yi alkawarin yin aiki da kyau ta wannan hanyar, saboda bayan lokaci ba za a sami raguwar bayanai ba.
