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.

  • 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). The technology was initially seen as extremely difficult to achieve, with doubts expressed about its feasibility in 2013. The regions being written must be heated in a tiny area - small enough that diffraction prevents the use of normal laser focused heating - and requires a heating, writing and cooling cycle of less than 1 nanosecond, while also controlling the effects of repeated on the drive platters, the drive-to-head contact, and the adjacent magnetic data which must not be affected. These challenges required the development of nano-scale surface plasmons (surface guided laser) instead of direct laser-based heating, new types of glass platters and heat-control coatings that tolerate rapid spot-heating without affecting the contact with the recording head or nearby data, new methods to mount the heating laser onto the drive head, and a wide range of other technical, development and control issues that needed to be overcome. HAMR's planned successor, known as (HDMR), or bit-pattern recording, is also under development, although not expected to be available until at least 2025 or later. HAMR drives have the same form factor (size and layout) as existing traditional hard drives, and do not require any change to the computer or other device in which they are installed; they can be used identically to existing hard drives. 20 TB HAMR drives were released in January 2021.

  • 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. HAMR-onderzoek werd onder andere gedaan door het Information Storage Industry Consortium[1]. (nl)
  • 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'orientamento magnetico.Le aziende che attualmente studiano questa tecnologia sono TDK, Seagate e Western Digital. Nel 2018 Seagate annuncia che produrrà commercialmente dei dischi rigidi da 100 TB con questa tecnologia per il 2025 quando ad oggi i dischi HAMR da 50TB sono ancora in fase sperimentale. (it)

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. Технология позволяет достичь плотности записи в 2,32—7,75 Тбит/см² (по прогнозам, соответственно, компаний «Hitachi GST» и «Seagate»). Такая плотность приведёт к возможности размещения от 37 до 50 ТБ данных на 3,5-дюймовых жёстких дисках и 12 ТБ на 2,5-дюймовых (одного жёсткого диска объёмом в 37 ТБ будет достаточно, чтобы записать на него в несжатом виде все материалы Библиотеки Конгресса США).
