CHAPTER 2 DESCRIPTION

This chapter summarizes general functions and key features of the Spinpoint V40 drive, as well as the standards and regulations they meet.

2.1Introduction

The Samsung SpinPoint V40 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 V40 family are 20.0,30.06,40.0,60.0,60.06 and 80.0 gigabytes of storage. Samsung defines a gigabyte (GB) as one billion bytes.

The SpinPoint V40 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 interface connectors are the standard 40-pin for AT Interface and 4-pin for DC power supplies.

The SpinPoint V40 incorporates Advanced GMR (Giant Magneto Resistive) head and Noise Predictive PRML (Partial Response Maximum Likelihood) signal processing technologies. These advanced technologies allow for an areal density of over 29.18 gigabits per square inch and storage capacity of over 40.06 gigabytes per disk.

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.
