Sony collaborates with Seagate to develop 30TB high-capacity hard drives

Views : 52
Update time : 2024-03-07 15:08:43
        The SONY Group will begin mass production of laser diodes that are expected to double the capacity of mechanical hard drives (HDDS) and meet today's demand for high capacity in data centers. SONY Semiconductor Solutions, which will begin producing the diodes in May in partnership with US firm Seagate Technology, will use the parts for 3.5-inch hard drives that can write more information than ever before, in terms of storage capacity, by mounting the semiconductor laser on the magnetic head where the HDD writes and reads information. 3.5-inch HDD capacity can reach 30TB, twice the previous capacity. SONY will invest a total of about 5 billion yen ($33 million) in semiconductor lasers for high-capacity HDDS at a plant in Miyagi prefecture, north of Japan's main island, and another in Thailand, so that new production lines can be installed.
 
 
      SONY's new technology is so precise that it can fire a laser at a spot as narrow as a millionth of a millimeter. It allows a laser of 400 degrees or higher to contact the storage area on the disk surface. In this way, more information can be written to the same area of the disk, allowing the hard disk to increase its data storage capacity.
       As more startups and companies train in generative artificial intelligence (AI), the demand for data centers is surging. Statista, a German research firm, estimates that global data generation will reach 181 zettab (Zetta is 10 to the 21st power) in 2025, a 90% increase from 2022.
         But data centers require a lot of land and electricity, making it difficult for developers to build more quickly. SONY's new HDD technology helps alleviate both of these requirements, with the ability to accurately fire a laser at a point of one millionth of a millimeter, allowing the laser to touch the disk surface at 400 degrees or more, thus writing more information in the same area and improving the data storage capacity of the hard drive. In addition, this new technology helps reduce the land and power requirements of data centers, reducing electricity consumption by about 40 percent. This innovation will lead to more efficient and environmentally friendly storage solutions for data centers.
