A CD marker pen, sometimes called a CD/DVD marker or disc marker pen, is specifically designed for writing on optical discs. Here are some important aspects to consider:
- Ink Type: CD marker pens use special ink that is quick-drying and resistant to smudging. The ink is often permanent and designed to adhere well to the disc’s surface without affecting its readability.
- Tip Size: These pens typically have a fine or ultra-fine tip to ensure precise writing. This helps avoid any interference with the disc’s surface or data layer.
- Non-Toxic: The ink is usually non-toxic and safe to handle, though it’s still best to avoid direct contact with skin or eyes.
- Disc Safety: The ink is formulated to be safe for the disc’s surface, but it’s still important to use the pen gently to avoid scratches or other damage.
- Labeling: Use the pen to write information such as the contents of the disc, the date, or any other relevant details.
