This Seagate laptop HDD is a high-capacity, high-performance random access storage device, which uses non-removable disks as storage media. Each disk incorporates thin film metallic media technology for enhanced performance & reliability. & for each disk surface there is a corresponding movable head actuator assembly to randomly access the data tracks & write or read the user data. The laptop HDD
Includes:: the AT controller embedded in the disk drive PCB electronics. The drive's electrical interface is compatible with all mandatory, optional & vendor-specific commands within the ATA
Specification. The laptop HDD incorporates Tu MR head & Noise Predictive PRML (Partial Response Maximum Likelihood) signal processing technologies. These advanced technologies allow ample storage capacity. The heads, disk (s), & actuator housing are environmentally sealed within an aluminum-alloy base & cover. As the disks spin, air circulates within this base & cover, commonly referred to as the head & disk assembly (HDA), through a non-replaceable absolute filter ensuring a contamination-free environment for the heads & disks throughout the life of the drive.
