Medalist Pro 2160N Product Manual, Rev. B 1
Introduction
This manual describes the functional, mechanical and interface specifications for the Medalist
®
Pro 2160N hard disc drive. The Medalist Pro
2160N is referred to in this manual by its model number, ST52160N.
Seagate desktop products take a step into the future with the ST52160N.
The drive features MR heads and PRML recording technology and uses
an Ultra SCSI interface that supports a synchronous external transfer
rate of up to 20 Mbytes per second.
The ST52160N has other features that ensure fast data throughput. The
drive uses a 128-Kbyte buffer and an adaptable cache that aids the flow
of read and write data. Embedded servo technology allow the dri ve to
position the heads for data retrieval efficiently and accurately while
eliminating the periodic thermal recalibration that can interr upt during
data transfers. The drive also uses a 16-bit microprocessor and an
intelligent controller that provides data streaming: direct dat a transfers
between the drive and the host without microprocessor intervention. This
feature allows for a sustained data rate that f acilitates video playback
and other multimedia operations.
The drive conforms to the standard 3.5-inch footprint but has a 0.75-inch
(19-mm) height profile and a 5. 380- inc h-dept h pr ofile. The lower height
and shorter depth gives the designer or integrator more room for air
circulation, other peripherals or a smaller drive bay.
The SCSI commands the drive supports are listed in Section 3.3. on
page 30.

1.6 Read look-ahead and caching
The drive uses an algorithm that improves seek performance by storing
data in a buffer and processing it at a more convenient time. Three
methods are used: read l ook-ahead, read caching and write caching.
These are described in Appendix C.6 on page 94.
1.7 Start/stop command
If the motor-start option is disabled, the drive is ready within 20 seconds
after power is appli ed. If the motor -start option is enabl ed, the drive is
ready within 20 seconds after it receives the Motor Start command. If the
drive receives a command to spin down or power is removed, the driv e
stops within 15 seconds.

1.7.1 Power-up sequence
The following typical power -up sequence is provided to assist you in
evaluating drive performance. This information does not constitute a
specification or a performance guarantee.
Power is applied to the disc drive.
1.
Depending on whether there is a jumper installed on pins 9 and 10 of
2.
the options jumper block (J5) shown in Figure 3 on page 19, either of
the following sequences occurs:
• If a jumper is not installed, the remote start option is not enabled, and
the drive begins to spin up as soon as power is applied.
• If a jumper is installed, the remote start option is enabled, and the drive
begins to spin up when the host sends a command for the motor to
start.
8 Medalist Pro 2160N Product Manual, Rev. B
3. Within 250 msec after power is applied, the drive responds to the Test
Unit Ready, Request Sense, Mode Sense and Inquiry commands.
4. The drive begins to lock in speed-control circuits.
6. The actuator lock releases the actuator.
7. The spindle motor reaches operating speed in about 5 seconds. After
5 seconds, there are no speed variations.
8. The drive performs velocity-adjustment seeks.
9. The drive seeks track 0 and is then ready.
1.7.2 Power-down sequence
Caution. Do not move the drive until the motor has come to a complete
stop.
1. The power is turned off.
2. Within 15 seconds, the drive spindle stops rotating.
3. The read/write heads automatically move to the landing zone, which
is inside the maximum data cylinder.
4. The magnetic acuator lock mechanism locks the arm. This completes
the power-down sequence.
1.7.3 Auto-park
During power-down, the read/write heads automatically move to the
landing zone. The heads park inside the maximum data cylinder and the
magnetic actuator lock engages. When power is applied, the heads
recalibrate to track 0.
1.8 Power managemen t
The drive supports power-management modes that reduce its overall
power consumption. They automatically change from one mode to
another in response to interface activity. You do not need to change any
parameters or send any special commands to make the drive change
modes. The power-management modes are described as follows:
• Spinup. Spinup is def ined as the period during which t he spindl e is
coming up to operating speed. The power consumed in this mode is
equivalent to the average power during the first 10 seconds after the
drive begins to spin up.
Medalist Pro 2160N Product Manual, Rev. B 9
• Seek. The servo electronics are active, and the heads are moving to
a specific location on the disc. The read/write electronics are powereddown. The power consumed in this mode is equivalent to the average
power measured while executing random seeks wit h a 2-revolution
(26.6 msec) dwell between seeks. T he drive enters this mode from
the Idle mode.
• Read/Write. The drive is reading or writing. All electronics are active
and the heads are on track.
• Idle. The motor is up to speed and the drive is in track-follow mode.
1.8.1 Power consumption
Values in the t able below were measured at the drive power connector
with an RMS DC ammeter. The terminating resistors are disabled, and
terminator power is supplied through the SCSI connector. All values are
measured 10 minutes after the drive spins up except as noted.

2.0 Hardware and interface
The ST52160N uses an Ultra SCSI interface that consis ts of an 8-bit
bidirectional data bus. The interface supports multiple initiators, disconnect and reconnect, self-configuring host software and logical block
addressing.
The Ultra SCSI interface uses a singled-ended driver/receiver configuration that uses asynchronous or synchronous communication protocols.
The ST52160N supports asynchronous transfer rates up to 10 Mbytes
per second and synchronous transfer rates up to 20.0 Mbytes per
second.
2.1 SCSI-3 compatibility
The drive interface is described in the Seagate SCSI-2 /SCSI-3 Interface
Manual, publication number 77738479. The drive complies with the
mandatory subset of the ANSI SCSI-2 Interface. The Fast SCSI-3
interface is based on the ANSI Small Computer System Interface-2
(SCSI-2), document number ANSI X3.131-1994.
2.2 Handling and static-discharge precautions
The drive has static-sensitive devices. Avoid damaging the drive and
these devices by obser ving the f ollowing standard handl ing and stati cdischarge precautions:
• Keep the drive in its static-shielded bag until you are ready to complete
the installation. Do not attach any cables to the drive while it is in its
static-shielded bag.
• Before handling the drive, put on a grounded wris t strap, or ground
yourself frequently by touching the metal chassis of a computer that
is plugged into a grounded outlet. Wear a grounded wrist strap
throughout the entire installation procedure.
Wool and synthetic clothes, carpets, plastics and Styrofoam contributes to electrostatic buildup. Static discharge may damage sensitive
components in your drive and computer.
• Handle the drive by its edges or frame only.
• The drive is extremely fragile—handle it with care. Do not press down
on the drive’s top cover.
• Always rest the drive on a padded, antistatic surface until you mount
it in the host system.
• Do not touch the connector pins or the printed circuit board.
18 Medalist Pro 2160N Product Manual, Rev. B
• Do not remove the factory-installed labels from the drive or cover them
with additional labels. If you do, you void the warranty. Some factoryinstalled labels contain information needed to service the drive. Others
are used to seal out dirt and contamination.
2.3 Electrical interface
The ST52160N is designed t o use single-ended int erface signals, s ingle-ended drivers and receivers, and active terminator circuitry. Figure 2
shows a single-ended transmitter and r ec eiv er without the active terminator circuitry.
•
Transmitter characteristics.
The drive uses an ANSI SCSI-compatible, open-collector, single-ended driver. This driver is capable of
sinking a current of 48 mA with a low-level output voltage of 0.4 volts.
•
Receiver characteristics.
