Introduction

The Samsung Winner 3A WA31273A / WA32543A / WA33203A / WA32163A /

WA31083A, Winner 2A WA32162A 3.5 inch disk drives are low cost, high capacity, high

performance random access devices which use non removable 3.5 inch disk(s) as storage

media. The disk is used of thin film metallic media technology for enhanced

performance. Each disk surface employs one movable head to access the data tracks. The

formatted capacity is 1.27, 2.54, 3.2, 2.16, 1.08, and 2.16 gigabytes of storage, respectively.

The Winner 3A WA31273A / WA32543A / WA33203A / WA32163A / WA31083A,

Winner 2A WA32162A drives include the AT controller embedded in the disk drive PCB

electronics. The drive's electrical interface is compatible with the mandatory, optional

and vendor specific commands.

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.

High capacity is achieved by using Advanced Thin Film Inductive head and PRML

(Partial Response Maximum Likelihood) recording method. This method can increase

capacity by increasing the areal density of the drive..

High performance and low cost are achieved through the use of a rotary voice coil

actuator and an embedded servo system. Embedded servo technology uses special

information recorded on each data cylinder to maintain position accuracy. This

technique assures recording head position accuracy in read or write operations at all

temperatures.

The heads, disk and actuator housing is environmentally sealed. Air circulates within

the HDA through a non-replaceable recirculating filter to ensure the maintenance of a

contamination free disk and actuator environment.
