摘要

FIELD: electronics. SUBSTANCE: electron device, for example, play device may reduce time of reading of visually identified information of designation formed on read-only storage with compact disc and may ensure protection, effective removal or exclusion of forged products. Electron device has unit for mounting of read-only storage on compact disc into which compact disc may be put with visually identified information; information detection unit detects special information selected from unit information composed of designation information and comparison unit storing basic data D corresponding to data A subject to comparison. Comparison unit compares special information with data A subject to comparison corresponding to basic data D and generates output signal of result of comparison. EFFECT: higher efficiency.
