Tape medium recording and/or reproducing apparatus capable of minimizing deviation of recording position

A tape medium recording and/or reproducing apparatus for recording or reproducing information on or from a plurality of tracks on a tape medium each of said plurality of tracks having first and second regions defined therein in a direction conforming to the direction of scan, each of said first regions having a positioning signal recorded therein while a tracking pilot signal is recorded in selected ones of the first regions, said tape medium recording and/or reproducing apparatus comprising:

• a rotatable cylinder;
• at least one magnetic head mounted on said cylinder for rotation together therewith, said magnetic head scanning the plurality of tracks successively to record or reproduce information on or from the second regions of the plurality of tracks on the tape medium and to reproduce the position signal from the first regions;
• a rotational position detector means for detecting a rotational reference position of said cylinder to provide a rotational reference position signal indicative thereof;
• a positioning signal detector means for detecting the position signal in response to a reproduction signal from said magnetic head and for outputting a reproducing position signal indicative of a timing at which the position signal has been detected;
• a reproduction timing generator means for generating a reproduction timing signal at a first timing determined by the reproducing position signal;
• a timing memory means operable in response to the reproduction timing signal and the reference position signal to measure and store a length of time from the timing, at which the rotational reference position of said cylinder has been detected, to said first timing and also to output a signal indicative of the length of time;
• a timing protector means for generating, when no positioning signal has been detected, a pseudo timing signal at said first timing and also for inserting the pseudo timing signal into the reproduction timing signal to provide a protection timing signal;
• a sample timing generator means for outputting a sample timing signal at a second timing determined by the protection timing signal;
• a tracking control means for controlling said magnetic head to appropriately scan a target track in reference to a level determined by leakage components of respective tracking pilot signals which have leaked into the reproduction signal from the neighboring first regions in which the tracking pilot signals had been recorded and which have then been sampled by the sample timing signal;
• an insert timing generator means for outputting an insert timing signal at a third timing determined by the protection timing signal;
• and
• an insert recording means for recording on the second region at a timing indicated by the insert timing signal.
