Medalist 1080sl SCSI Product Manual, August 1995

Introduction

This manual describes the functional, mechanical and interface specifi-
cations for the Medalist 1080sl SCSI hard disc drive. The Medalist 1080sl
SCSI is referred to throughout this manual by its model number,
ST51080N.
The ST51080N is a high-capacity, high-performance, energy-efficient
SCSI drive that comes in the mini 3.5-inch form-factor.
The drive uses a high-performance SCSI-2 interface that supports an
asynchronous external transfer rate of up to 5 Mbytes per second and a
synchronous external transfer rate of up to 10 Mbytes per second.
The interface is supported with a 128-Kbyte segmented cache and
embedded servo technology. The segmented cache aids the flow of read
and write data. The embedded servo allows for accurate positioning of
the heads over the data and eliminates periodic thermal recalibration to
assure data transfer without interruption.
The ST51080N conforms to the standard 3.5-inch footprint but have a
0.75-inch (19 mm) height profile and a 5.0-inch depth profile. The lower
height and shorter depth gives the designer or integrator more room for
air circulation, other peripherals or a smaller drive bay.
The following is a summary of the drive's features:
