Heat-assisted magnetic recording (HAMR) (pronounced "hammer") is a magnetic storage technology for greatly increasing the amount of data that can be stored on a magnetic device such as a hard disk drive by temporarily heating the disk material during writing, which makes it much more receptive to magnetic effects and allows writing to much smaller regions (and much higher levels of data on a disk). 20 TB HAMR drives were released in January 2021.

  • Der englischsprachige Begriff heat-assisted magnetic recording (HAMR, deutsch Wärme-unterstützte Magnetaufzeichnung) bezeichnet ein Verfahren zur Speicherung von Informationen in magnetischen Werkstoffen, das noch größere Datendichten bei Festplatten ermöglichen soll. Seagate demonstrierte Sommer 2002 erstmals Labor-Technik mit HAMR. Im Jahr 2013 wurden erste Serienmodelle angekündigt, welche mit Stand 2022 bislang nur als Kleinserie verfügbar sind. (de)

  • 热辅助磁记录 (HAMR) 是一種使用鐳射熱先加熱高度穩定媒體,以輔助磁性錄寫資料的技術。HAMR 技術需要像鉑鐵合金這樣高度穩定的磁性複合材料。這些材料可以在相當小的面積內儲存單一位元組而不再受限於超順磁性;目前使用在硬碟儲存的許多技術仍受限於超順磁性。唯一的缺點是,他們必須被加熱以適應磁場方向的改變。 HAMR 是富士通在2006年發展出來的技術,這項技術可以達到每平方英吋1Tb的儲存密度。 (zh)

  • HAMR è un'abbreviazione per Heat-Assisted Magnetic Recording. Descrive una tecnologia che registra dati magneticamente con un'alta stabilità usando un . La tecnologia HAMR potrebbe incrementare il limite di memorizzazione magnetica di 100 volte, arrivando così a una densità di memorizzazione di 50 terabit per pollice quadro. Prodotti commerciali che utilizzano questa tecnologia sono previsti a partire dal 2018.La tecnologia di HAMR gode del vantaggio dell'alta stabilità dei componenti magnetici. Questi componenti possonomemorizzare gruppi di bit in un'area più piccola senza essere affetti dagli stessi effetti del superparamagnetismo che affligge solitamente i dischi hdd tradizionali. Questo è possibile riscaldando tramite un laser termico i materiali prima di eseguire cambiamenti nell'orie (it)
  • HAMR of Heat Assisted Magnetic Recording is een methode waarbij men met een laser een harde schijf verwarmt waardoor de schijf makkelijker magnetisch te beschrijven valt en de snelle afkoeling na het schrijven de data stabiliseert. De HAMR-technologie is als eerste toegepast door Seagate die verwacht hierdoor de zogenaamde , de oppervlakte waaronder het magnetische veld instabiel wordt, tot een factor 100 op te schuiven. Dit zou toekomstige datadichtheden van 7,75 terabits per vierkante millimeter (50 terabits per vierkante inch) mogelijk moeten maken. (nl)
  • Термомагнитная запись (также тепловая магнитная запись, магнитная запись с подогревом; англ. HAMR (heat-assisted magnetic recording)) — гибридная технология записи информации, комбинирующая магнитное чтение и магнитооптическую запись.Применяется в перспективных НЖМД большой (от 15—20 Тб) ёмкости.
