Abstract
A helical scanning magnetic recording apparatus utilizing Azimuth recording technology includes a reading head and a writing head which are arranged with a predetermined dimensional relationship. When the recording to a recording tape, the reading head and the writing head simultaneously record a first track and a second track beside the first track. Since the writing head is located on the upper stream side than the reading head, the writing head can be tracked on the next track position when the, reading head is placed over the first and second tracks such that the reading head reproduces the first and second tracking signals having the same amplitude.
