Magnetic recording and/or reproducing apparatus |
摘要 |
A magnetic recording and/or reproducing apparatus has compatibility with a conventional analog signal recording/reproducing VTR and can realize an operation mode in which a digital signal is recorded and/or reproduced. During N-times long time recording, the travel speed of a magnetic recording medium is set to 1/N of that during normal recording to perform recording every N scanning operations of a rotary head and during N-times long time reproduction, the travel speed of the magnetic recording medium is set to 1/N of that during normal recording and the travel of the magnetic recording medium is controlled such that the level of a reproduction signal reproduced every N scanning operations of the rotary head at a predetermined timing is maximized so as to reproduce a reproduction signal at that timing.
