Using this Guide

This guide covers the use and operation of the
RMO-S594-DW/S591-DW Magneto-Optical
Disk Unit (called the “disk unit” thereafter). Do
not attempt to use the disk unit without first
carefully reading this guide. When finished, keep
it handy for future reference.

The guide is divided into the following sections.

Chapter 1 Introduction

This chapter contains a general overview of the
RMO-S594-DW/S591-DW disk unit, touching
upon its features, system configuration, and the
location and function of its parts.

Chapter 2 Getting Started

This chapter explains how to connect the disk
unit to the host computer and other SCSI
peripheral devices. It also explains how to set the
disk unit’s functions and the SCSI ID. Refer to
this chapter when setting up the disk unit.

Chapter 3 Using the Disk Unit

In this chapter, you learn how to turn on the disk
unit, and how to insert and eject a disk cartridge.
Refer to this chapter when you are ready to
actually begin using the disk unit.

Chapter 4 Precautions

This chapter contains precautions regarding the
use and operation of the disk unit and magneto­optical disk cartridges.
It also discusses cleaning of disks.
Be sure to refer to this chapter before using the
disk unit.

Appendix

The Appendix contains an explanation of the disk
unit’s main specifications.

Notes:

• The manufacturer disclaims all responsibility
for any losses incurred through malfunction or
use of this product.

• The manufacturer does not warrant the security
of data stored using this product. To guard
accidental data loss, frequent backup of
important data is highly recommended.

whole or in part, is prohibited.

Chapter 1 Introduction 5

Chapter 1 Introduction

Overview

Features

The RMO-S594-DW/S591-DW Magneto-Optical
Disk Unit has the following features:

• Magneto-optical technology enables repeated
writing and erasing of data on the disk.

• The disk unit automatically senses the type of
disk being inserted, enabling the free use of
both 650-Mbytes (594-Mbytes), 1.3-Gbytes
(1.2-Gbytes) and 2.6 Gbytes (2.3 Gbytes)disks
indifferently.

• Direct-Overwrite MO disks can be used. The
writing performance of this disk unit is 1.5 to

2.0 times faster than that of the earlier MO Disk
Unit.

• A maximum of 2.6 Gbytes (1,024 bytes/sector)
or 2.3 Gbytes (512 bytes/sector) of data can be
written on the two sides of a 5.25-inch magneto­optical disk. This is equivalent to about 1600–
1800 times the capacity of a conventional 3.5­inch floppy disk (2HD).

• Any disk conforming to the internationally
accepted CCS (continuous/composite servo) or
CCW (continuous composite write-once) format
can be used in this disk unit.

• This disk unit employs SCSI-2 (Small
Computer System Interface-2).

• The 3,600 min

-1

(3,600 rpm) high-speed

spindle motor enables data transfer rates of

2.03 – 4.06 Mbytes/s (1,024 bytes/sector) or

1.78 – 3.56 Mbytes/s (512 bytes/sector).

• The low-profile, light-weight optical pick-up
yields average seek times of 25ms.

• Use of a highly reliable error correction code
(ECC) system keeps the error rate as low as
10

-12

.

• Optimum operation environment is provided
through use of a large, 4MB(S594-DW)/
1MB(S591-DW) buffer and optimized cache
control algorithm. (Write cache can be enabled
or disabled. For details, see “Setting the Disk
Unit’s Functions” on page 11.)

6 Chapter 1 Introduction

System Configuration

The disk unit should be used with a host
computer equipped with SCSI.

A maximum of seven peripheral devices can be
linked in a daisy chain on the SCSI bus, and
controlled with SCSI-2 commands.

3 BUSY indicator

As this disk is inserted and the drive becomes
ready for read/write operation, the BUSY
indicator turns green. The orange lamp lights
up when the disk unit is accessing or writing
data. This lamp flashes on and off at about 2­second intervals when the unit overheats,
regardless of whether or not a disk is being
accessed.

4 Disk insertion slot

Insert the disk cartridge into this slot. Refer
to the section “Inserting a Disk Cartridge” on
page 13 for more information.

5 Emergency eject hole

If the disk cartridge cannot be ejected using
the EJECT button 6, turn off the power and
insert the supplied emergency eject tool into
this hole to trip the emergency eject
mechanism. Refer to the section “What to do
if the disk does not eject” on page 14 for
further details.

6 EJECT button

Press this button to eject the disk cartridge
from the disk unit. The EJECT button is
disabled with the function switch or software
settings prohibit ejection. When the write
cache is enabled, it may take a few moments
(up to 45 seconds) for the disk to eject
because data in the cache must first be
written to the disk.

Setting the SCSI ID

The factory default setting for the SCSI ID is “0.”
If necessary, this ID number can be changed
using the SCSI ID switch on the rear panel. Be
sure to turn off the power before making any
changes.
Pushing the “+” button raises the ID number;
pushing the “–” button lowers the ID number.

Notes:

• The disk unit will not operate properly unless
the SCSI ID has been set correctly.

• Make sure to select a SCSI ID that has not been
assigned to another SCSI device.

Fig 2-4: Function Switches

This disk unit is equipped with a write cache.
When the write cache is enabled, never turn off
the disk unit power without making sure that all
data has been written to the disk from cache
memory. Data will be lost if you turn off the
power before all data in cache memory has been
written to the disk.
Before powering off the disk unit, be sure to eject
the disk. Ejecting the disk writes data from cache
memory to the disk.

Note:

Even though the drive will flush data periodically
to the disk, data may be lost in the case of a
power failure.

1 Press the POWER switch located on the left

side of the front panel.
This turns on the disk unit and causes the
POWER indicator to light up.

2 Start up the host computer. Refer to the

manual supplied with the host computer for
the start up procedure.

Chapter 3 Using the Disk Unit

Inserting a Disk Cartridge

3 Insert a disk cartridge with the side you want

to use facing upwards.

Fig 3-2: Inserting a Disk Cartridge

4 Access or write data on the disk using

software commands on the host computer.
The BUSY indicator lights up while the unit
is accessing the disk.

■ What to do if the disk unit stops

operating

When the temperature in the disk unit exceeds
the preset level, the BUSY indicator starts
flashing on and off at about 2-second intervals,
regardless of whether or not a disk is being
accessed, and the disk unit stops operating.
If this happens, you should improve the
ventilation of a setting area.
If the disk unit still refuses to operate, unplug the
unit and contact your dealer.

To use Side A, insert the
disk with “A” facing
upward.

Press th POWER
switch

14 Chapter 3 Using the Disk Unit

Ejecting a Disk Cartridge

Eject the disk cartridge either by using software
commands or by pressing the EJECT button.

Fig 3-3: Ejecting the Disk Cartridge Using the EJECT

button

Note

Do not attempt to eject a disk cartridge while the
BUSY indicator is lit orange (except when it is
flashing at about 2-second intervals due to
overheating). Ejecting the disk while it is being
accessed may cause data write errors or may
result in loss of data.
Also, it may take a few moments (up to 45
seconds) for the disk to eject when the write
cache is enabled, because data in the cache must
first be written to the disk.

■ What to do if the disk does not

eject

The disk cartridge may not come out, even when
you press the EJECT button or use a software
command, under the following conditions:

• The eject function has been disabled using the
function switch or a software command;

• The host computer is not functioning properly;

• The disk unit has been turned off (due to a
power failure, etc.); or

• Something is wrong with your disk unit itself.

When you cannot eject the disk cartridge using
the EJECT button or software commands,
remove it as follows.

1 Turn off the disk unit if the power is still on.
2 Insert the emergency eject tool (or a paper

clip) straight into the emergency eject hole to
trip the manual ejection mechanism.

Fig 3-4: Inserting the Emergency Eject Tool

This should cause the disk cartridge to eject.

Caution

The tip of the emergency eject tool is sharp.
When handling the tool, please be careful to
avoid injury.
