Abstract
Magnetic recording/reproducing apparatus has a lower drum, an upper drum equipped with a rotary magnetic head and being coaxially and rotatably supported by the lower drum, a first tilt driving device for tilting a center axis of the upper and lower drums at a predetermined angle to allow a rotary locus of the rotary magnetic head to coincide with a recorded track on a magnetic tape, a lead ring having a first tape positional regulation surface for guiding a reference edge of the magnetic tape, the lead ring being independently provided close to an outer peripheral surface of a small diameter section of the lower drum, and a second tilt driving device for tilting the lead ring to allow the first tape positional regulation surface thereof to match the reference edge of the magnetic tape. The apparatus has a constructive feature that a second tape positional regulation surface is at least provided at an end of a tape contacting area in a tape inlet side of the lower drum for guiding the reference edge of the magnetic tape running at the highest magnification speed in a trick play reproduction mode with respect to a tape speed of a normal recording.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
