    Abstract: The optical data recording method comprising the steps of: modulating data to be recorded, to generate a plurality of recording modulation codes; and emitting a pulse-like light beam to an optical disc, so that a plurality of recording marks and spaces which have lengths corresponding to the plurality of recording modulation codes are formed on the optical disc. In the optical data recording method, at least two of the plurality of recording marks 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.

    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: Drive information is updated to always include the recording/playback conditions determined from the most recent learning process. The data recording medium 101 has a data recording area 104 for recording data, and a drive information area 401 for recording drive information 401a. The drive information 401a includes a plurality of drive-specific information records 401b. Each of the plural drive-specific information records 401b defines the operating conditions of the data recording and playback apparatus when a data recording and playback apparatus that can load and access the data recording medium 101 reads or writes data. The plural drive-specific information records 401a are arranged chronologically according to when the information was recorded to the data recording medium 101.
