Title: Multitrack helical scanning device
Inventor: RI CHINKU
IPC: G11B5/86
Filed: 1994-11-16
Abstract: PURPOSE: To copy video signals at a high speed by scanning tracks on a magnetic tape corresponding to the rotation of a head drum assembly adaptively by the number of video heads mounted on the head drum assembly. CONSTITUTION: The head drum assembly 50 is provided with the 2N pieces of the video heads arranged along the outer peripheral surface of an upper drum 16 and the heads are in mutually confronting positional relationship, separated at the angle of 360 deg./2N and arrayed. The N corresponds to the multiple exponent of a tape transfer mechanism 30. Assuming that N=2, the head drum assembly 50 is provided with the video heads CH1, CH2, CH3 and CH4, the CH1 and the CH3 face each other and the CH2 and the CH4 face each other. Since the magnetic tape 20 is moved over the assembly 50 at the N folds of a standard speed, the respective heads CH1-CH4 trace the track at each 350 deg./2N rotation of the assembly 50. Thus, the four pieces of video field information displayed by T1-T4 are scanned during each rotation cycle of the assembly 50.  In such a manner, the multiple tracks of the magnetic tape 20 are scanned.
