In [[telecommunication]],s and [[computing]] a '''machine-readable medium''' ('''automated data medium''') is a [[Recording medium|medium]] capable of storing [[Data (computing)|data]] in a '''machine-readable format''' that can be accessedreadable by ana automated sensingmechanical device and(rather capablethan ofby beinga turned into (practically in every casehuman) some form of binary.

Examples of machine-readable media include (a)magnetic media such as [[Disk storage|magnetic disk]]s, cards, [[magnetic tape|tapes]], and [[magnetic drum|drums]], (b) [[punched card]]s and [[paper tape]]s, (c) [[optical disk]]s, (d) [[barcode]]s and (e) [[Magnetic Ink Character Recognition|magnetic ink characters]].

Common machine-readable [[data storage device|data storage]] and [[data transmission|transmission]] technologies include magnetic recording, processing [[waveform]]s, [[optical character recognition]] (OCR) and [[barcode]]s. Any information retrievable by any form of energy can be machine-readable. Examples include:
