Chapter 1 Introduction

Overview

Features

The RMO-S551 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), 2.6 Gbytes (2.3 Gbytes), and 5.2 Gbytes (4.8 Gbytes, 4.1 Gbytes) disks indifferently.
• A maximum of 5.2 Gbytes (2,048 bytes/sector), 4.8 Gbytes (1,024 bytes/sector), or 4.1 Gbytes (512 bytes/sector) of data can be written on the two sides of a 5.25-inch magneto-optical disk. This is equivalent to about 2900–3700 times the capacity of a conventional 3.5-inch 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 3,300 min ^-1 (3,300 rpm) high-speed spindle motor enables data transfer rates of 2.48 – 5.07 Mbytes/s (2,048 bytes/sector), 2.31 – 4.79 Mbytes/s (1,024 bytes/sector), or 1.97 – 4.06 Mbytes/s (512 bytes/sector).
• With disk capacities under 2.6 Gbytes (2.3 Gbytes), the spindle motor rotates at 3600min^-1 (rpm).
• 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 buffer and optimized cache control algorithm. (Write cache can be enabled or disabled. For details, see “Setting the Disk Unit’s Functions” on page 10.)

If the disk unit still refuses to operate, unplug the unit and contact your dealer.

Ejecting a Disk Cartridge

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

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.

On the Disk Unit

Safety Considerations

■ Power supply

• Be sure to use 100 - 240V AC.
• Do not share the AC outlet with any other power-consuming equipment such as copying machines or shredders.

■ AC power cord

• Be careful not to place or drop heavy object on the power cord, or subject it to anything that may damage it.
• When unplugging the cord from an AC outlet, be sure to grasp the plug itself. Pulling on the cord may cause damage to the internal wiring.
• Unplug the unit when not using it for long period of time.

■ Handling the emergency eject tool

The tip of the emergency eject tool is sharp. When handling the tool, please be careful to avoid injury. Do not use the tool for any purpose other than ejecting disks.

Damage Prevention

■ Do not subject the disk unit to shock or vibration

Dropping the unit or subjecting it to strong impact may damage the disk unit.

■ Setting position

The disk unit is designed to be used in the horizontal position. Do not position it at an angle.

■ Location requirements

Careful consideration should be given to the following in selecting a site to install or store your disk unit.

Avoid the following conditions:

• High humidity
  • High temperatures
• Direct sunlight
  • Dust
• Strong vibration
• Wide temperature fluctuations

Ventilation

Care should be exercised to prevent the internal mechanisms of the disk unit from overheating. Be careful not to clog or block the vent, or place the unit in an area with poor ventilation. The disk unit may stop operating altogether if the internal temperature becomes too high.

Condensation

Avoid subjecting the disk unit to extremes in temperature. If, for example, the disk unit is moved suddenly from a very cold location to a warm one, moisture from condensation may form within the unit due to the quick rise in ambient temperature. If a sudden change in the temperature cannot be avoided, wait for an hour or more before using the disk unit. Inserting a disk cartridge into the mechanism when moisture is present may cause damage to both the disk and the disk unit. Remove the disk cartridge immediately if you suspect any condensation problems. The moisture should evaporate quickly if the disk unit is left on without a disk inserted.

■ Moving the disk unit

Be sure to remove the disk cartridge when the disk unit is not being used. Also never move or transport the unit with the disk cartridge still inserted.

While in operation, the disk rotates at a high speed. Moving the disk unit at such a time may disturb the spinning disk and cause it to be damaged. Always remove the disk cartridge before moving your disk unit.

■ If problems occur

If any problems occur, turn off the power and unplug the disk unit, contact your dealer.

Other Points Requiring Attention

■ Electrical noise

The high-frequency signal generated by the disk unit may cause interference or static on other electrical appliances such as radios, televisions and audio tuners. If this should occur, move the disk unit a little farther away from the affected appliance.

■ Maintenance

Clean the cabinet with a dry soft cloth, or with a soft cloth lightly moistened with a mild detergent solution. Do not use any type of solvent, such as alcohol or benzine, which may damage the finish.

On the Disk Cartridges

• Do not drop the disk cartridge or subject it to any violent shocks or vibration.
• Do not disassemble the disk cartridge. It is a precision component and has been carefully adjusted at the factory prior to shipment.
• Do not open the disk cartridge's shutter manually or touch the disk inside. The shutter is designed to open automatically when the cartridge is inserted into the disk unit.
• Do not use the cartridge under ambient conditions of high humidity or wide temperature fluctuations. Moisture from condensation may make it impossible to read or write data.
• Avoid inserting and ejecting the disk cartridge more than is necessary.
• Always eject and remove the disk cartridge from the disk unit after using it.

■ Storing disk cartridges

• Store the disk cartridges in their cases.
• Do not leave the cartridges exposed to direct sunlight or excessive heat, like on the dashboard or in the glove compartment of an automobile. Do not store the disk cartridges under the following conditions.
  – Excessive dust and debris
  – Exposure to direct sunlight
• Near a heat source
  – High humidity

Protecting Your Data

The magneto-optical disk cartridges are equipped with a DATA PROTECT switch (red tab) to prevent accidental erasure of data on the disk or inadvertent writing of unwanted data. Slide this switch in the direction of the arrow as illustrated below to enable the write protect function.

You can still read the data contained on the disk, but will not be allowed to write on or erase the disk. Return the switch to its original position to disable the write protect.

Make it a practice to leave the write protection enabled when you do not foresee the need to write on the disk.

Dust and stains may accumulate on MO disks when they are used for a long period of time. To avoid resultant data read/write errors, use an optional disk cleaner. To maintain the high performance and prolong the useful life of your MO disk, cleaning at least once every three months is recommended.

■ Disk cleaning accessories

Use the following Sony disk cleaning kit or disk cleaner (sold separately).

• MOA-D51 Disk Cleaning Kit Do not use any other type of disk cleaner as it may cause data read/write errors due to the differences in disk surface characteristics. For cleaning instructions, refer to the manual supplied with each cleaning accessory

Attention

In the disk unit, preventive measures are taken to guard against dust. It is unnecessary to clean the optical lens of your disk unit. Using a lens cleaning cartridge may damage the disk unit.
