Abstract
A tape head having offset transducer spans between adjacent modules of the tape head that serves to maintain the balance between debris removal and reduced magnetic layer/recording device spacing on the one hand and reduced tape/tape head friction on the other hand. In one aspect, opposite edges of each module are relatively sharper adjacent the transducer span and relatively rounded (e.g., less sharp) away from the transducer span. The sharp edges reduce magnetic spacing loss and scrape debris off of the tape while the rounded edges reduce or eliminate contact between the tape and the head in regions where no transducer spans are present and thus where no tape writing or reading would be taking place.
