摘要： In a magnetic recording device and method, a magnetic reproduction method and its method and a tape recording medium, the performance can be improved. In the case of successively and obliquely forming tracks along the longitudinal direction of a second magnetic tape having a width wider than a first magnetic tape and continuously recording recording data for at least two tracks in a digital recording format on each track, each track is to be formed at a predetermined track pitch set based on the recording time and the reproduction signal characteristic. Thereby, recording data based on the digital recording format which is applied to the first magnetic tape can keep a practically sufficient C/N ratio and can be recorded on the second magnetic tape for a long time. And thus, a magnetic recording device and method, a magnetic reproduction device and method, and a tape recording medium capable of improving the performance can be realized.

摘要： Picture image data having high image quality is recorded in a disk-shaped recording medium such as a hard disk and a removable disk. A recording apparatus is arranged by a first unit for recording image data with respect to a disk-shaped recording medium in which an outer peripheral sided region thereof is recordable/reproduceable at a higher rate than that of an inner peripheral sided region thereof, and a second unit for designating an attribute of image data recorded in the disk-shaped recording medium. When the second unit designates image data having a large data amount per unit time, the first unit records the image data having the large data amount per unit time in the inner peripheral sided region of the disk-shaped recording medium, whereas when the second unit designates image data having a small data amount per unit time, the first unit records the image data having the small data amount per unit time in the inner peripheral sided region of the disk-shaped recording medium.

摘要： A data recording and reproducing apparatus for recording and reproducing video signals in a plurality of formats with different rates to/from a record medium is disclosed. In the data recording and reproducing apparatus, a video signal in a selected format is converted into video data packets and audio data packets whose lengths are optimally designated corresponding to the selected format. With a video data packet and an audio data packet, a video sync block and an audio sync block whose lengths are different are formed, respectively. The video sync block and the audio sync block are encoded with respective error correction codes. The resultant data is recorded as record data to a record medium. Corresponding to the data rate of the video signal, at least one data packet is placed in one video sync block. A synchronization detecting apparatus automatically and accurately detects sync blocks with different lengths from a data sequence of record data reproduced from a record medium. The synchronization detecting apparatus separates the detected sync blocks into video sync blocks and audio sync blocks. The video sync blocks and the audio sync blocks are decoded with respective error correction codes. As a result, video data and audio data are restored.
