Overview

Features

Introduction

The Sony BW-RS101/BW-RU101 “Professional Disc for DATA” Unit comes with the following features.

• The “Professional Disc for DATA” external optical disc unit uses a shortwave blue violet laser with a wavelength of 405 nm.

• The powerful objective lens used for focusing the laser beam has a numerical aperture of 0.85, resulting in a track pitch of only 0.32 µm. This makes writing as much as 23.3 GB of data on one side of a disc possible.

• A 0.1 mm cover layer enables a high tilt tolerance.

• The overall thickness of the 120 mm discs is 1.2 mm and the recording layer has a cover layer of only 0.1 mm thick. This effectively increases the margin of error when the disc tilts or bends. Tilt tolerance is thus enough to enhance reliability for read/write operations.

• The BW-RS101 uses SCSI-3 (Ultra 160 LVD/SE SCSI).

• The BW-RU101 uses Hi-Speed USB (USB 2.0).

• The seek time in the CAV is 110 ms (1/3 stroke) or 200 ms (full stroke).

• In CLV mode, the high-speed spindle motor allows for a 9 MB/s write data transfer speed and a 10.8 MB/s read data transfer speed.

• In CAV, the high-speed spindle motor allows for 4.5 to 9 MB/s write data transfer speed and 4.5 to 10.8 MB/s read transfer speed.

Connecting the Unit

Connecting the BW-RS101

You can connect the unit to one host computer through a SCSI bus that has up to 15 devices connected in a daisy chain.

Note

Before connecting the unit, make sure to turn off the unit and all the other devices on the SCSI chain.

Connect a SCSI cable to the SCSI connecter of the unit to connecting a host computer or another SCSI device.

If the unit is the last device on the SCSI daisy chain, connect the supplied terminator to one of the SCSI connecters as illustrated below.

Chapter 2 Getting Started

SCSI Cables

SCSI Terminator

Connect the AC power cord to the AC IN connector on the unit.

You can use a 68-signal conductor, flat cable or a 34-signal twisted cable as the LVD/SE cable. To achieve a high transfer rate, the total length of SCSI cables should not exceed 6 m in a SE configuration. In a LVD SCSI configuration, the cables should not exceed 12 m.

If the unit is the last device on the SCSI daisy chain, be sure to connect the supplied terminator or a separately purchased terminator because the unit has no internal terminator. The unit will not operate properly unless you use the appropriate terminator.

Note

If you use a terminator other than the one supplied with the unit, be sure to only use a terminator that conforms to SPI3:ANSI NCITS:336:2000.

Connecting the Unit

Connecting the BW-RU101

Chapter 2 Getting Started

Connect the unit to the host computer through a USB cable. You can use a USB Hub to connect up to 127 USB devices. Because BW-RU101 supports hot-plug, you can plug in, use, and unplug BW-RU101 without having to shut down the host computer.

Note

Before connecting the unit, make sure that it is off.

Connect the USB cable to the USB connector of the unit.

Connect the AC power cord to the AC IN connector of the unit.

USB Cables

To achieve high transfer rate and stable operations, the length of the USB cables should not exceed 5m.

Even though BW-RU101 is a hot-plug device, data may be lost when unplug the USB cable, so confirm the following items before unplug the USB cable.

• Data saved to the disc is not accessed from an application or software.

Setting Functions/SCSI ID

• Background Formatting This unit is equipped with a background formatting function. To improve the reliability of writing data, executing a physical format before using an unused disc is highly recommended. If you disable the background formatting function, you can start the physical format in the foreground by issuing the FORMAT command. During the format, the unit scans whole sectors of the disc to detect any defect sectors and register them as defective sectors. It takes around 80 minutes to complete. If you enable the background formatting function, the unit starts the physical format automatically in the background without having to receive the FORMAT command. Therefore, you can even read and write data during the format. It takes at least 135 minutes to complete.

Cautions

• Background Formatting Precautions

Chapter 2 Getting Started

Never turn off the unit without making sure that the disc is removed when the disc is in the background formatting process. The unit may not write data properly and mark them as the defective sectors if you turn off the unit without ejecting the disc during the background formatting. Before turning off the unit, be sure to eject the disc using the EJECT command or pressing the eject button.

• Inhibit Verify Using a physical formatted disc is highly recommended if you inhibit verify for writes. Although disable verify for writes quicken the write transfer rate, but may reduce the reliability of written data. Even if you inhibit verify for writes, if the disc is not physical formatted, the drive forces verify for all write operations.

• Write Cache Precautions This unit is equipped with a write cache function. When the write cache is enabled, never turn off the unit power without making sure that all data has been written to the disc from the cache memory. Data will be lost if you turn off the power before all data in cache memory has been written to the disc. Before turning off the unit power, be sure to eject the disc, as this writes data from cache memory to the disc. Further, even though the unit will periodically flush data from cache memory periodically to the disc, data may be lost in the case of a power failure.

• Do not share the AC outlet with any other power-consuming equipment such as copying machines or shredders.

Handling the Power Cable

• Take care not to place or drop anything heavy on the power cable or to damage the cable. Using a damaged cable is dangerous.

• Be sure to hold the plug when disconnecting the power cable from the outlet. Pulling the cable may damage the cable.

• When the unit is not to be used for a long time, disconnect the power cable from the outlet.

Chapter

Location

The unit must be placed horizontally or vertically on a flat, stable surface. The maximum permissible mounting tilt is 10° for the bottom placed surface.

Location requirements

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

• High humidity

• High temperatures

• Direct sunlight

•Dust

• Strong vibration

• Wide temperature fluctuations

Do not subject the unit to shock or vibration

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

Unit Usage Precautions

Ventilation

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

Moving the unit

Be sure to remove the disc cartridge when the unit is not being used. Also never move or transport the unit with the disc cartridge still inserted. While in operation, the disc rotates at a high speed. Moving the unit at such a time may disturb the spinning disc and cause it to be damaged. Always remove the disc cartridge before moving your unit.

Condensation

Avoid subjecting the unit to extremes in temperature. If, for example, the 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 unit. Inserting a disc cartridge into the mechanism when moisture is present may cause damage to both the disc and the unit. Remove the disc cartridge immediately if you suspect any condensation problems. The moisture should evaporate quickly if the unit is left on without a disc inserted.

Chapter 3 Usage Precautions

Temperature Alarm

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

Cleaning the Unit

Do not use a lens cleaning devices. The internal lens cleaning brush mechanism ensures periodic, automatic cleaning of the pickup lens. Therefore thee is no need to clean the lens of the unit. Using a lens cleaning devices may damage the lens. Make sure cleaning products are not used to clean a disc or the lens of the unit.

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.

If problems occur

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