A strong short light pulse can record data on a magnetic layer of yttrium iron garnet doped with Co-ions. The novel mechanism outperforms existing alternatives allowing ever fastest write-read ...

Magnetic recording relies on using an applied magnetic field to reverse the magnetisation of a piece of magnetic material. The speed at which data can be written depends on how quickly the applied ...

Professor Emeritus Shunichi Iwasaki and Tom Coughlin at PMR Milestone Ceremony in Sendai. On October 9, 2023 I attended the IEEE Engineering Milestone for Perpendicular Magnetic Recording (PMR) in ...

Toshiba demonstrated a method for using magnetic fields from microwave radiation to reverse the magnetization direction selectively in a multi-layer magnetic recording media at the International ...

Microwave-Assisted Magnetic Recording (MAMR) employs a high-frequency magnetic field to lower the effective switching field of recording media, enabling the use of smaller, high-coercivity grains and ...

Scientists have demonstrated a new recording principle that improves recording efficiency by 35% by combining spin torque with conventional heat-assisted magnetic recording (HAMR). This advancement is ...

A team of physicists from the Vienna University of Technology (TU Wien) has simulated a magnetic recording process for data storage that could drastically increase the storage density of hard drives.

Storing data on magnetic tape might seem more antique than cutting edge, but with more data in the world than ever, it could still be one of the most energy efficient and secure storage methods we ...

Seagate, using its new shingled magnetic recording (SMR) technology to cram more data into fewer platters, is preparing to launch an 8TB hard drive priced at just $260. For that low-low price (just ...

Hot stuff Heat-assisted magnetic recording is set to boost the storage capacity of hard disks still further. (Courtesy: Seagate Technology) When it comes to storing data, you might think that magnetic ...

Use left and right arrow keys to seek audio. We've covered Seagate's HAMR, or Heat-Assisted Magnetic Recording, tech for HDDs, which is set to breathe new life into traditional platter-based storage ...
