摘要:
An optical disk comprising: a first substrate, a data zone formed on said first substrate, and a second substrate, wherein said data zone is formed between said first substrate and said second substrate. A spiral track formed on the data zone, and a barcode pattern is formed by a laser on the spiral track, and which is readable by a pick-up for reading data recorded on the data zone together with a method for reproduction of the data from such an optical disk.

[PROBLEMS] To provide a magnetic head provided with a microprocessor capable of storing a firmware downloaded from an external server. [MEANS FOR SOLVING PROBLEMS] The magnetic head has a core which is provided with a coil for converting data stored in a magnetic card to analog signals, an A/D conversion chip which is connected to the core to convert the analog signals to digital signals, and the microprocessor which is connected to the A/D conversion chip. The processor has a firmware storage means. When the firmware which controls its arithmetic/storage functions and controls an external hardware is downloaded from the external server (11) to the magnetic head, the firmware storage means stores the firmware.
摘要:
A method for producing an optical disk comprising a first data zone including data signals readable by light radiation and a second data zone in which barcode-like marks are formed, wherein said barcode-like marks partially overlap the first data zone and are formed after completion of the manufacturing of the said optical disc.

Presented is a playback device capable of encrypted media content distribution that includes a processor, a decryption algorithm stored in memory, multiple units of encrypted media content preloaded on a storage device, a decoder that decrypts the media content using a decryption key, a receiver and remote control apparatus. A user obtains the decryption key from a remote system, which can be an authorization system that provides the decryption key after the user provides payment. A user account exists on the remote system, which automatically charges the user account and provides the decryption key upon receiving a media content selection and an account number or a personal identification number from the user.
