摘要： A digital data recording apparatus records digital data in tracks on a tape. Each track has a first signal area for storing track format information and a second signal area for storing a plurality of sync blocks. The apparatus includes a circuit for inserting, in the first signal area, regular TDS information indicating the track data structure of digital data, and a circuit for inserting, in the final sync block, backup TDS information having the same structure as the regular TDS information.

摘要： The video signal input is converted to high-speed reproduction data by a high-speed reproduction data encoder 1. The video signal input is converted to high-speed reproduction data by a formatter 2, which formats the high-speed reproduction data so that the same data is recorded to n tracks. After the recorded data is input to an error correction encoder 3, it is decoded by a decoder 4 and recorded by a recording head 5 to the magnetic tape 6. During reproduction, the recorded data is reproduced by reproduction head 7 from the magnetic tape 6, and decoded by decoder 8. The decoded data is then error corrected by an error correction decoder 9, and then input to a deformatter 10. The deformatter 10 separates the normal reproduction data from the high-speed reproduction data, and separately outputs both data types. During normal reproduction, the normal reproduction data is output by a switch 13; the high-speed reproduction data is decoded to video data by a high-speed reproduction data decoder during high speed reproduction, and output.

摘要： A plurality of digital signals having total data rates of n bit/s or less are input to a digital recording device recording digital signals having a data rate of n bit/s. The digital signals are subjected to format-conversion for the digital recording device to be recorded therein. Furthermore, signals having a data rate of n/i.sub.1 bit/s or less are subjected to format-conversion to be recorded i.sub.1 times in the digital recording device. In the case where the data rate of the digital signals to be input is n/j bit/s, the digital signals are subjected to format-conversion so that the amount of data capable of being recorded per unit time is decreased by i/j; thus, the digital signals are recorded for a long period of time under the condition that the data recording time is prolonged j times. Furthermore, when input data to be recorded on a magnetic tape at a normal data rate by using a magnetic head mounted on a rotary cylinder is recorded, the recording device of the present invention makes it possible to select a plurality of types of track angles generated by the rotation number of the cylinder, the tape traveling speed, and the like.

摘要： In order to reproduce highly important information easily and at high speed, such information is composed into data of fixed length and is assigned from the beginning of a block. Without increasing the recording rate, in order to record a signal so that the highly important information may be reproduced securely, a dummy sync block is inserted immediately before a data sync block which contains the highly important information for defining or explaining the content of the signal to be recorded. To maintain the error correction capability in a normal play mode, moreover, the sync block composition which is the same as in the signal to be recorded is used for the highly important information. In particular, as for such information, by assigning the information in plural sync blocks, reproduction is securely realized also in the case of a trick play mode.
