SpinPoint V80 drives include a controller built into the drive PCB electronics. Transmission of electricity interface is compatible with all mandatory, optional and vendor-specific commands in the ATA specification. Drive size in line with industry standard 3.5-inch form factor. SpinPoint V80 includes Advanced GMR (giant magneto resistive) head, and noise, input PRML (partial response maximum) signal processing technology. These advanced technologies that allow real density of about 60 gigabits per square inch and a capacity of over 80.06 gigabytes on a disc. It also includes 48-bit LBA over 137GB capacity. The heads, disk (s) and drive housing is environmentally sealed within a framework of aluminum alloy and coatings. As the disc spin, the air circulating inside the base and coating, which is usually referred to as the head and disk assemblies (HDA) through nesemnyh absolute filter pollution free environment for the heads and disks during the lifetime of the disk.
