Storage media classification — Evaluate the statement: "An optical disk is an example of magnetic storage."

Introduction:
Storage media are broadly categorized by their physical recording mechanisms. Magnetic storage (hard disks, tapes) encodes information using magnetic domains, while optical storage (CD, DVD, Blu-ray) uses pits and lands read by lasers. The prompt asks whether an optical disk is an example of magnetic storage, which tests understanding of these mechanisms.

Given Data / Assumptions:

• Optical disks: CD/DVD/Blu-ray use optical reflectivity changes.
• Magnetic media: HDDs, tapes use magnetization direction changes.
• Hybrid media like magneto-optical exist but are distinct devices.

Concept / Approach:
Optical disks store data as physical or phase-change features that alter reflectivity. A laser detects the differences to reconstruct bits. No magnetic field changes are used in standard optical formats. Therefore an optical disk is not a magnetic storage device. Magneto-optical disks are a separate technology combining magnetic fields with laser heating, but the general term "optical disk" refers to purely optical schemes in mainstream products.
