CDRW or re-writable CDs are less widely used today outside of the home or the office. Today's big players are write-once CDs, or CDR.

The CD disc is actually just a small, transparent plastic disc. Very cheap and easy to make. The plastic disc becomes a CDR when a foil film is coated onto the disc's top side. It is interesting that most people are careful to protect the underside of their discs from scratches, abrasions and other damage.

Using the wrong pen or spilling any substance to the top side of a cheap silver disc can cause immediate damage, so be warned. CD Media of a higher quality will have a coated top side that will ensure the integrity of the data under normal day to day conditions. Be warned however that some white topped CDR discs can be very cheap mixed media almost picked off the manufacturing plant floor, or from dodgy importers who want to make a quick buck.
Unbranded CDR is usually bought in packs of 100 in a cello wrap. Often described as being on a spindle the media will usually arrive spindle less - the term is really a figure of speech. Unbranded CDR from a good source will be ideal for most daily purposes. Without guarantee however it should be avoided where you require long term data integrity.
