Abstract: A data recording method by which data of a compact disk can be recorded well onto a magneto-optic disk of the ISO format. Data of a compact disk are recorded onto a 5-inch magneto-optic disk (ISO format) of the 512 bytes/sector type of the CS system. The sector size of the magneto-optic disk is 610 bytes.      Data included in one sector (98 frames) of the compact disk are 2.352 bytes and subcodings of P to W are 96 bytes. Data for one sector are divided into data groups A to H to construct a data format. A CRC is added to each data group. Further, a parity 2 (Reed-Solomon node) is added. Data (3,050 bytes) for one sector of the compact disk to which the CRCs, parities and so forth are added are recorded across 5 sectors of the magneto-optic disk. Data of a compact disk can be recorded onto a magneto-optic disk having a different sector size. and since error correction codes or error detection codes are added using the remaining area, the data can be recorded with a high degree of accuracy.

Abstract: An ignition timing control system controls igintion timing of spark plugs of an internal combustion engine associated with a plurality of changeover devices, changeover of an operative state of each of which has influence upon output torque of the engine.  Operating conditions of the engine are detected.  A basic ignition timing advance value is calculated based on results of detection of the operating conditions of the engine.  A changeover of the operative state of each of the changeover devices is detected.  A correction value for correcting the basic ignition timing advance value for suppressing the engine torque is calculated, in response to results of detection of the changeover of the operative state of each of the changeover devices. The largest one of a plurality of the correction values calculated is selected to a final correction value to be used for correcting the basic ignition timing advance value, when changeovers of the operative states of at least two of the changeover devices are detected substantially at the same time.
