All About Recordable Compact Discs
Philips is a trusted Dutch multinational technology company that has been around for more than a century, manufacturing lighting products, healthcare products, and audio products, including accessories for your media needs. Whether you are recording data files or creating music files for your personal use, you need recordable CDs in your collection.What is the difference between a CD-R and a CD-RW?
A CD-R is recordable media while a CD-RW is rewritable. The logic behind CD-RW media is that you can write data and important files on it and rewrite over them when you want so that the process is not closed. Conversely, CD-Rs allow you to record whatever you would like, but once the files have been recorded, they cannot be deleted or written over.What kinds of things can you record on Philips CDs?
You can record a variety of things for single use:
- Music files, including .mp3s, .mp4s, and .wave files
- Movies, videos, and personal copies of your favorite DVDs
- Data files of all types
The storage capacity of a typical CD is 74 minutes of audio or 650 megabytes (MB) of data. The most common capacity is 80 minutes of audio or 700MB of data, but there are some larger capacity choices available, such as 90 minute/790MB and 99 minute/870MB discs.Can you record data in multiple sessions?
The number of recording sessions that you can have on your media depends on the writing method used.
- Disc-at-once: The entire CD is written in one session with no gaps and the session is closed, transforming the CD-R into a read-only CD.
- Track-at-once: Data is written one track at a time and the session is left open. This allows future recordings.
- Packet writing: Used to record data to a disc in "packets." This also allows more data to be added at a later date.
The average lifespan of a compact disc is 10 years; this number changes based on the type of the product. Also, after CDs have been burned, they begin to degrade. CD-Rs have an internal layer of dye for data storage. When that dye degrades, the data may become unreadable. The reflective surface may also cause failure. Most CD manufacturers use silver as a reflective surface, but it is also more likely to oxidize so that the surface wont reflect anymore.Content provided for informational purposes only. eBay is not affiliated with or endorsed by Philips.
