Introduction

The Samsung SpinPoint P80 3.5 inch disk drives are high capacity, high performance random access storage
devices, which use non-removable 3.5-inch disks as storage media. Each disk incorporates thin film metallic
media technology for enhanced performance and reliability. And for each disk surface there is a
corresponding movable head actuator assembly to randomly access the data tracks and write or read the user
data. The formatted capacities of the SpinPoint P80 family are 40.0, 80.0, 120.0 and 160.0 Gigabytes of
storage. Samsung defines a Gigabyte (GB) as one billion bytes.
The SpinPoint P80 drives include the AT controller embedded in the disk drive PCB electronics. The drive's
electrical interface is compatible with all mandatory, optional and vendor-specific commands within the ATA
specification.
Drive size conforms to the industry standard 3.5-inch form factor. The 40-conductor or 80-conductor AT
interface connectors are used depending on the transfer mode.
The SpinPoint P80 incorporates Advanced GMR (Giant Magneto Resistive) head and Noise Predictive
PRML (Partial Response Maximum Likelihood) signal processing technologies. These advanced
technologies allow for an a real density of about 60 Gigabits per square inch and storage capacity of over
80.06 Gigabytes per disk. It also incorporates 48 bit LBA for over 137GB capacity.
The heads, disk(s), and actuator housing are environmentally sealed within an aluminum-alloy base and
cover. As the disks spin, air circulates within this base and cover, commonly referred to as the head and disk
assembly (HDA), through a non-replaceable absolute filter ensuring a contamination free environment for the
heads and disks throughout the life of the drive.
