The Difference Between Recordable vs Rewritable CD

CDs have been a trusted choice for storing and sharing data for years.

Unfortunately, not all CDs are created with the same quality standards.

You may have encountered two types of CDs when looking for storage solutions – recordable and rewritable.

Here, I will discuss the variations between these two kinds of CDs, so you can determine which one best suits your requirements for your upcoming project.

Recordable vs Rewritable CD

First, let’s define what we mean by “recordable” and “rewritable” CDs.

Recordable CD

A CD-R, otherwise known as a recordable CD, is a versatile and cost-effective digital storage medium that allows users to write data onto it just once.

With its ability to store up to 700 megabytes of data, the CD-R is ideal for storing large amounts of information in one place.

Once the information is written on the blank disc, it cannot be changed or erased, making it an ideal storage solution for archiving and preserving important documents and data.

Rewritable CD

A rewritable CD, on the other hand, also known as a CD-RW, can be written to and erased multiple times.

A CD-RW offers a convenient and cost-effective way for users to store, share, and transport data.

Unlike a traditional CD-ROM, which can only read data from the disc, a rewritable CD can be written to and erased multiple times. This makes it ideal for backing up files or sharing information with others.

Additionally, since the discs can be reused many times over, they are an excellent choice for businesses looking to save money on storage costs.

Differences Between a Recordable vs a Rewritable CD

Now that we have a basic understanding of recordable and rewritable CDs, let’s take a deeper dive into the manufacturing process.

Recordable CDs are essentially blank discs that have a special dye coating. This dye can be “burned” by a laser, which in turn creates tiny pits that can be identified as data by CD players.

On the other hand, rewritable CDs are made with a special phase-change material that can be melted and re-cooled by a laser. This process allows the data to be rewritten multiple times.

So, what are the benefits of each type of CD?

Recordable CDs are a good way to store data that will not be changed or altered in any way. Since the data recorded on them can’t be modified once it’s written, you don’t have to worry about it being erased or lost.

Additionally, they’re perfect for creating audio CDs and making backup copies of important files.

However, a downside to using recordable CDs is their inability to be modified once the data has been recorded. This means that any mistakes are permanent and can’t be undone.

Unlike regular CDs, CD-RWs are perfect for storing data that may need to be altered in the future. This type of CD allows you to overwrite the existing data several times. So if updates need to be made at a later time, you have the freedom to do so.

They are also good options for making backups and storing unfinished work.

But, one of the main drawbacks is that data on them can be inadvertently erased or could not be read by a player.

  • Choosing between a recordable and rewritable CD mostly comes down to what you need the CD for. If you are burning an audio CD or archiving important information that won’t need altering, then a recordable CD is ideal.
  • For temporary backups or files which may require editing in the future, rewritable CDs are typically a better choice than regular CDs.

Before using a rewritable CD, make sure to double-check your device’s ability to read it. Not all CD players and computers are compatible with this type of disc, especially if they’re older models.

It pays to be vigilant when it comes to checking the specifications of your device before using any type of disc.


Despite the advancements in technology, CDs are still an effective and popular way of backing up and transferring data. USB drives, cloud storage, and other digital storage solutions have all become available in recent years but CDs remain a trusted source for storing and sharing information.

Today, you can find two types of CDs, recordable and rewritable, at most electronic stores or online shops.

So, both recordable and rewritable CDs are excellent choices for data storage or sharing. Nonetheless, they have their own advantages and disadvantages that need to be considered.

Recordable CDs are a perfect choice if you need to store data that you don’t expect to be modified. On the other hand, rewritable CDs can come in handy if you anticipate needing to make changes to your data soon.

Before making a decision, evaluate your needs and determine which type of CD would best suit those needs.
