摘要： A magnetic recording and/or reproducing element comprises a main element body, and windings wound around the main element body. The main element body has a pair of extremely thin layers made from a ferromagnetic material, and the extremely thin layers oppose each other at respective edges thereof so as to constitute a gap. Each of the thin layers are sandwiched between a pair of support members which are made from a non-magnetic and abrasion proof material. A contact surface is formed on a vertex part of the main element body, for making contact with a magnetic recording medium so as to record and/or reproduce a signal on and/or from the magnetic recording medium. The main element body has one or a plurality of side surfaces which form a predetermined angle with respect to the contact surface and define the peripheral edge of the contact surface so that the contact surface has a predetermined shape with an extremely small area and has the gap at an approximate center of the predetermined shape.

摘要： The present invention relates to a magnetic recording/reproducing apparatus capable of performing a fast forward reproduction, a fast backward reproduction, a still picture reproduction and the time-lapse recording. The magnetic recording/reproducing apparatus according to the present invention realizes a preferred reproduced image containing no noise-bar, by correcting deviation of magnetic heads mounted on an upper drum from intended tracks depending on a difference in tape running speed between a recording operation and a reproducing operation by tilting the upper drum about a predetermined pivot point with respect to a lower drum having a lead formed thereon. Further, the magnetic recording/reproducing apparatus according to the present invention realizes a preferred reproduced image containing no noise-bar even for a signal recorded in a narrow track pattern in an extended time recording mode, by correcting a slight separation of the magnetic tape from the lead due to a tilt of the upper drum, by tilting the lower drum.

摘要： A magnetic recording and reproducing apparatus with a positioning mechanism for a tape guide drum is provided. The positioning mechanism includes first and second actuators which changes the position of the tape guide drum relative to a direction of travel of a magnetic tape during reproduction for orienting rotary magnetic heads to follow tracks formed on the magnetic tape perfectly if the tracks are curved undesirably. The first actuator is designed to turn the tape guide drum to orient a portion of a rotation plane of the rotary magnetic heads at a tape-entering position where the magnetic tape enters the tape guide drum in a first direction and a portion of the rotation plane at a tape-leaving position where the magnetic tape leaves the tape guide drum in a second direction opposite the first direction. The second actuator is designed to turn the rotation plane of the rotary magnetic head at the tape-entering position and the tape-leaving position in the same direction.

摘要： A video signal recording apparatus uses a crosstalk component reproduced from an adjacent pre-recorded track to control the position of a track which is newly formed when successively forming closed loop tracks on a rotary recording medium, and records a video signal amounting to one field on each track so that out of two mutually adjacent tracks making up a track pair, a signal related to an odd (or even) field out of signals which are related to two consecutive fields and constitute a picture is recorded on one track of the track pair and a signal related to an even (or odd) field out of signals which are related to two consecutive fields and constitute a picture is recorded on the other track of the track pair, so that signals amounting to one frame are recorded on the track pair.
