Abstract
An information processor including a processing device for recording information on a recording medium or reproducing the information recorded on the recording medium, is provided with: an encrypting/decrypting device which is capable of an encrypting operation for encrypting the information to be recorded when the information is recorded on the recording medium and a decrypting operation for decrypting the information to be reproduced from the recording medium when the information is reproduced from the recording medium; the processing device which includes the two or more encrypting/decrypting devices; a control device which controls the encrypting/decrypting device so as to perform one of the encrypting operation and the decrypting operation; and a switching device which switches a transmission path of the information to the encrypting/decrypting device in response to one of the operations performed by the encrypting/decrypting device.
