Introduction
This manual describes the functional, mechanical and interface specifi­cations for the Medalist hard disc drives. The Medalist Pro 2160N is referred to in this manual by its model number ST52160N. This drive comes with the standard 50-pin interface connector. The Medalist Pro 2160WC is referred to in this manual by its model number ST52160WC. This drive comes with the 80-pin blindmate single-connector attachment (SCA-2).
Seagate desktop products take a step into the future with the ST52160N and ST52160WC. These drives feature MR heads and PRM L r ecording technology.
The Medalist Pro drives uses an UltraSCSI interface. The ST52160N supports a synchronous external transfer rate of up to 20 Mbytes per second. The ST52160WC supports a synchronous external transfer rate of up to 40 Mbytes per second.
These drives have other features that ensure fast data throughput. The ST52160N uses a 128-Kbyte buffer. The ST52160WC uses a 256-Kbyte buffer. The adaptable cache aids the flow of read and write data. Embedded servo technology allows the drives to position the heads for data retrieval efficiently and accurately while eliminating the periodic thermal recalibration that can interrupt during data transfers. These drives also use a 16-bit microprocessor and an intelligent controller that provides data streaming: direct data transfers between the drive and the host without microprocessor intervention. This feature allows for a sus­tained data rate that facilitates video playback and other multimedia operations.
Pro 2160N and Medalist Pro 2160WC SCSI
The drives conform to the standard 3.5-inch footprint but have a 0.75-inch (19 mm) height profile and a 5.380-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 SCSI commands the drives support are listed in Section 3.3. on page 36.

1.5 Seek time
All seek time measurements are taken under nominal conditions of temperature and voltage with the drive mounted horizontally. In the following table:
Track-to-track
seek time is the average of all possible singl e-track
seeks in both directions.
Average/typical
seek time is a true statistical random average of at least 5,000 measurements of seeks in both directions between ran­dom cylinders, less overhead.
Full-stroke
seek time is one-half the time needed to seek from logical
block address zero (LBA 0) to the maximum LBA and back to LBA 0.

Host overhead varies between systems and cannot be specified. Drive internal overhead is measured by issuing a no-motion seek. Drive overhead is typically less than 1.0 msec.

1.6 Read lo ok-ahead and caching
The drives use algorithims that improve seek performance by storing data in a buffer and processing it at a more convenient time. Three methods are used: read look-ahead, read c aching and write caching. These are described in Appendix C.6 on page 108.
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 enabled, 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 drive stops within 15 seconds.

1.15 FCC verification
The Medalist Pro SCSI interface drives are intended to be contained solely within a personal computer or s imilar enclosure (not at tached to an external device). As such, a drive is c onsidered to be a subassembly even when individually marketed to the customer. As a subassembly, no Federal Communications Commission authorization, verification or cer­tification of the device is required.
Seagate Technology, Inc. has tested the drive in an enclosure as described above to ensure that the total assembly (enclosure, disc drive, motherboard, power supply, etc.) does comply with the limits for a Class B computing device, pursuant to Subpart J of Part 15 of the FCC rules. Operation with noncertified assemblies is likely to result in interfer­ence to radio and television reception.

radio frequency energy and, if not installed and used in strict accordance with the manufacturer’s instructions, may cause interference to radio and television reception.
This equipment is designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or television, which c an be determined by turning the equipment on and off, you are encouraged to try one or more of the following corrective measures:
Reorient the receiving antenna.
Move the device to one side or the other of the radio or TV.
Move the device farther away from the radio or TV.
Plug the equipment into a diff erent outlet so that the receiver and
computer are on different branch outlets.
If necessary, you should consult your dealer or an experienced radio/tele­vision technician for additional suggesti ons. You may find helpful the following booklet prepared by the Federal Communications Commission:

2.0 Hardware and interface
The Medalist Pro drives use an UltraSCSI interface. The ST52160N consists of an 8-bit bidirectional data bus. The ST52160WC consists of a 16-bit bidirectional data bus. The interface supports multiple initiators, disconnect and reconnect, self-configuring host software and logical block addressing.
The UltraSCSI 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. The ST52160WC supports asynchronous transfer rates up to 20 Mbytes per second and synchronous transfer rates up to 40 Mbytes per second.
2.1 SCSI-3 compati bil ity
The drive interface is described in the Seagate SCSI-2 /SCSI-3 Interface Manual, publication number 77738479. The drives comply 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 observing t he following 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 wrist 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.
18 Medalist Pro 2160N/2160WC Product Manual, Rev. A
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.
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 drives are designed to use single-ended interface signals. They use single-ended drivers and receivers and active terminator circuitry. Figure 2 shows a single-ended transmitter and receiver without the active terminator circuitry.
Transmitter characteristics.
The drives use 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.
The drives use an ANSI SCSI single-
ended receiver with hysteresis gate or equivalent as a line receiver.
The loss in the cable is defined as the difference between the voltages of the input and output signals, as shown below:

The ST52160N and ST52160WC drives are differentiated by their con­nectors. The ST52160N comes with a standard 50-pin interface connec ­tor and a standard 4-pin power connector. The ST52160WC comes with an 80-pin blindmate single-connector attachment (SCA-2) . The power is supplied to the driv e through the bus. To minimize noise, us e shielded mating connectors.
