Q & A for batteries

A: Ni-CD stands for Nickel Cadmium, Ni-MH stands for Nickel-Metal Hydride. Nickel-Metal Hydride batteries have no Cadmium added. Cadmium is hazardous to the environment.

A: Nickel Cadmium batteries must be recycled. Call 1-800-8-BATTERY or visit too find the recycling centers or participating national retailers.

There are currently no restrictions on the disposal of Nickel-Metal Hydride batteries.

The Rechargeable Battery Recycling Corporation (RBRC) recycles the following portable rechargeable battery chemistries:

Nickel Cadmium (Ni-Cd)
Nickel Metal Hydride (Ni-MH)
Lithium Ion (Li-ion)
Small Sealed Lead (Pb)*
* weighing less than 2 lbs./1 kg.

These batteries are commonly found in cordless power tools, cellular and cordless phones, laptop computers, camcorders, digital cameras, and remote control toys.

A: No, however if using a Nickel Cadmium charger to charge Nickel-Metal Hydride batteries, charging should be monitored to avoid overcharging.

A: Memory Effect on a battery is the loss off run time per charge over the life of the battery. To avoid Memory Effect and attain maximum performance discharge battery completely each use.

Nickel-Metal Hydride has no Memory Effect and can be charged or topped-off at any time without affecting battery life.

A: Nickel-Metal Hydride (Ni-MH) batteries provide up to 200% more power than Nickel Cadmium (Ni-CD) rechargeable batteries, will significantly outperform alkaline batteries, in most digital applications and will greatly outperform Ni-CD batteries in high-drain applications.

Ni-MH batteries have a rechargeable life of up to 1000 cycles, 25% more than Ni-CD.

Ni-MH batteries have no Cadmium added. Cadmium is hazardous to the environment.

Very economical batteries that can be reused approximately 1,000 times

You can recharge them approximately 1,000 times and the per-unit cost is approximately 4 JPY.In addition, end-of-life eneloop batteries can be recycled and they are thus really environmentally friendly next-generation batteries

Q & A for CD’s

A: Ideally suited to the multimedia age, CD-R is a high capacity recording media which meets the storage requirements of video, audio, and data.

CD-R officially stands for Compact Disc Recordable, basically a CD upon which recording can be performed. However, data can be written only once to the disc, and data can not be erased or rewritten. (Additional writing to the disc is possible if enough capacity remains.) Almost all other recording media can be rewritten, so CD-R (once written upon) can be played back in a music- use CD player or CD-ROM drive. CD-R is said to be the optimal media due to distribution possibilities, the huge installed base of CD, its highly durable unalterable data characteristics, and suitability for archive use.

A: About 650MB of Data can be recorded onto one CDR 650 disc (74 minutes.) This is the equivalent to 450 1.44 MB floppy discs.

A: To record on a CD-R, the CD-R drive employs a laser beam with the same wavelength as that used when reading a CD (780mm), yet at a much higher strength. And to guide the laser, the CD-R disc features a spiral groove molded into its surface, unlike a pressed CD. When recording, the laser focuses on the disc, generating heat to above 300º on only the affected region. This causes the organic dye (found in the recording layer) and the substrate of that small area (0.6 microns wide) to be physically altered. Not surprisingly, the optical characteristics (refractive index) of that area are also altered and this is the difference between “burned” and “not-burned” areas which is recognized by the CD-R drive.

A: Do not touch the recording surface and keep the disc free of dust and fingerprints. If dirty, clean the surface with canned air. Do not damage of dirty the substrate side. Cleaning by wiping the surface is not recommended. If wiping is required use a CD-cleaner cloth and wipe the disc from the inside to the outside, perpendicular to the tracks. Do not wipe in a circular motion around the disc, as this may permanently damage the disc. If a cleaning liquid is necessary, use the one that is for cleaning CD’s. Sudden changes in humidity or temperature are not recommended, as this may cause the disc to warp or water to condense on the disc.

A: Do not write on the disc using a pencil or hard topped pen. If writing on the disc is required , use a felt tipped pen on the protective layer surface. Do not attempt to erase anything that has been written on the disc.

If you will be using any adhesive labels or stickers, some precautions should be taken: Labels must be perfectly adhered to the disc surface. Any bubbling or creasing will imbalance the disc which can cause tracking errors or noisy spin ups. Never attempt to remove an adhered label. In addition, as with writing pens, insure your labels adhesive does not contain any chemical solvents that can become absorbed into the dye later.
