Although optical drives are less common today, they’re still covered on the exam and used in legacy and specialty environments. This episode explores the different types of optical media—CD, DVD, and Blu-ray—and explains the distinctions between read-only, writable, and rewritable formats. We also discuss capacity limits and common labeling conventions such as DVD-R and CD-RW.

Drive technologies are examined in terms of laser wavelength, spin speed, and error correction capabilities. We also walk through typical use cases, troubleshooting common optical drive failures, and identifying media issues like scratches or unreadable discs. This episode prepares you to handle exam questions that reference legacy or archival media configurations with accuracy and confidence. Brought to you by BareMetalCyber.com.
