A head drum construction for use in a magnetic recording and reproducing apparatus such as a VTR apparatus comprises a rotatable drum having first and second axially opposite surfaces, a recording magnetic transducer such as a recording magnetic head mounted on the rotatable drum for recording information signals on a magnetic tape, a playback monitoring magnetic transducer such as a reproducing magnetic head mounted on the rotatable drum for reproducing, with a time delay, the information signals recorded on the magnetic tape by the recording magnetic transducer, a first signal transmission path connected to the recording magnetic transducer and disposed on the first surface, and a second signal transmission path connected to the playback monitoring magnetic transducer and disposed on the second surface.

A tape loading device for a recording and/or reproducing apparatus, comprises a loading mechanism for drawing out a tape from a tape cassette which has supply and take-up reels, and for loading the tape unto a predetermined tape path, brakes for respectively braking reel discs which rotate the reels, tension controllers for respectively controlling tensions in the tape which is drawn out from the reels, a detector for detecting an arrival of the loading mechanism to an intermediate position, and a control circuit. The control circuit makes one brake operative and the other brake inoperative during a first half of an operation stage in which the tape is drawn around the periphery of a guide drum, and makes both brakes inoperative and both tension controllers operative during a latter half of the operation stage. The first half of the operation stage continues until the detector detects the arrival of the loading mechanism to the intermediate position, and the latter half of the operation stage continues until the tape loading operation is completed. The one brake brakes one reel disc which rotates one reel from which a certain tape path extends, which certain tape path increases its length as the tape loading operation progresses and is one of a pair of tape paths which are formed as the tape is drawn out from each of the reels.

A display device for a magnetic tape recording and/or reproducing apparatus, comprises a pulse generating circuit for generating a pulse signal having a frequency which is in accordance with a rotational speed of a capstan which drives a magnetic tape to travel in a state where the magnetic tape is pinched between the capstan and a pinch roller, a counter for counting the pulse signal from the pulse generating circuit, and an indicator for displaying a counted result in the counter. The counter counts the pulse signal from the pulse generating circuit so as to obtain a counted result which would result in a real-time display on the indicator. The indicator displays in real-time, a tape travel quantity of the magnetic tape which is driven to travel by the capstan.
