Recording media

Recording media refers to the physical material used to store digital or analog data, such as images, audio, or video. Examples include CDs, DVDs, Blu-ray discs, hard drives, USB flash drives, and memory cards. These devices save information via different technologies—whether reflecting light, magnetizing surfaces, or encoding electrical charges—allowing data to be read, written, and erased as needed. The choice of media depends on factors like storage capacity, speed, durability, and portability, making them essential for data preservation, transfer, and backup across various applications.
