    Abstract: To provide a memory-writing device which can simply and reliably write desired data to a nonvolatile memory of an electronic device, connection is made with an ECU to perform write processing to write write data from the memory-writing device to a flash ROM by copying a write-control program from the external portion to a RAM and executing the write-control program, and by sequentially sending the foregoing write-control program and write data to this ECU together with sending, at a predetermined timing, write-control information required for the ECU to execute the write-control program, the write-control program and the write-control information are stored in a freely attachable and removable first ROM and the write-control information stored in the first ROM is read and sent to the ECU at a memory-rewriting device to cause the write processing to be performed in the ECU. According to this device, an ECU of differing specifications can be supported merely by exchanging the first ROM.

    Abstract: A data storage medium is provided on which data is to be recorded by modulating the data to generate a plurality of recording modulation codes and irradiating a pulse-like light beam to the data storage medium, so that a plurality of recording marks and spaces which have lengths corresponding to the plurality of recording modulation codes are formed on the data storage medium. At least two of the plurality of recording marks are formed by the light beam emitted according to a recording pulse train. The recording pulse train comprising a first pulse which is disposed at a front and forms a leading edge of the recording mark, a last pulse which is disposed at a backend and forms a trailing edge of the recording mark, and a multi-pulse train which is disposed between the first pulse and the last pulse and forms a center of the recording mark. The multi-pulse train has a pulse period longer than T which represents a reference period of the recording modulation code. The plurality of recording marks have different lengths represented by T with each other. A number of pulses in each of the recording pulse trains is increased by one as the recording mark is increased in length by 2T. A shortest recording mark and a second shortest recording mark are constituted of a single pulse, respectively.

    Abstract: A data storage medium is provided on which data is to be recorded by modulating the data to generate a plurality of recording modulation codes and irradiating a pulse-like light beam to the data storage medium, so that a plurality of recording marks and spaces which have lengths corresponding to the plurality of recording modulation codes are formed on the data storage medium. The data storage medium comprises a disc information area that includes a region on which at least one of an irradiation information of the light beam to form the recording marks and a constitution information of the recording mark is to be recorded. At least two of the plurality of recording marks are formed by the light beam emitted according to a recording pulse train. The recording pulse train comprises a first pulse which is disposed at a front and forms a leading edge of the recording mark, a last pulse which is disposed at a backend and forms a trailing edge of the recording mark, and a multi-pulse train which is disposed between the first pulse and the last pulse and forms a center of the recording mark. The multi-pulse train has a pulse period longer than T which represents a reference period of the recording modulation code. The plurality of recording marks have different lengths represented by T with each other. A number of pulses in each of the recording pulse trains is increased by one as the recording mark is increased in length by 2T. A shortest recording mark and a second shortest recording mark are constituted of a single pulse, respectively. Each of the multi-pulse trains has an equal pulse width and pulse interval in the plurality of recording marks.

    Abstract: An optical disk and a method for identifying the optical disk are provided which make it possible to identify a recording system of the optical disk easily in a short time by a recording and reproduction apparatus when a groove-recording system and a land-recording system are both employed in one kind of optical disk, for, example, a BD-R. Specifically, the polarity upon reproducing the wobble information is made to be the same in both of the optical disk of groove-recording system and the optical disk of land-recording system. The recording system of the optical disk that shows the same wobble polarity irrespective of the recording system can be easily detected by finding a tracking polarity that can recognize the wobble information by changing the tracking polarity, whereby the start-up time of the recording and reproduction apparatus can be shortened.
