Western Digital revealed recently that it has begun to sample its next-generation hard drives based on microwave assisted magnetic recording (MAMR) technology. The sampling is a prelude to mass production, which will see the first commercial HDDs based on the tech released this year. Meanwhile, the company is working on hard drives featuring two actuators that will arrive in 2020 or later. Overall, Western Digital remains confident in MAMR and expects to launch multiple generations of such drives. In the meantime, the firm is also admitting that it has continued to invest in development of alternative heat assisted magnetic recording (HAMR) technology.
“We are sampling our 16 TB [MAMR-based] product today,” said Michael Cordano, president and CEO of Western Digital, at the company’s meeting with financial analysts last month.
As expected back in 2017, the first MAMR-powered drives will feature 16 TB capacities and will use eight platters, which was confirmed by the executive during the event. Western Digital’s 16 TB HDD will be aimed at nearline applications and are intended for cloud datacenters as well as enterprises that require massive storage capacities. However Mr. Cordano did not clarify whether the MAMR-powered HDDs were only sampling with select customers (for example, Western Digital’s SMR-based HDDs are available only to select clients), or if they were being offered to a broader spectrum of clients.
