A network interface cassette for coupling signals between a wireless network and a tape head in a cassette tape player. The network interface cassette includes an enclosure that is conformed to the cassette tape form factor. It contains a transceiver that converts base band signals for radio frequency communications within the wireless network. It also contains a network controller that is coupled to communicate the base band signals with the transceiver. The network controller converts digital audio signals to and from the base band signals. There is an audio processor that converts the digital audio signals to analog audio signals. A coupling means converts the analog audio signals to magnetic audio signals. The coupling means is aligned to couple the magnetic audio signals to the tape head. A power supply with batteries and a generator driven from the cassette player capstan are provided. A wireless user interface adapter is provided to couple microphone and audio signals to the apparatus. Plural communications requests are processed, and include a priority scheme to manage resource contention.

A tape head designed for transducing data on a magnetic recording tape that is subject to tape dimensional changes. The tape head includes two or more arrays of transducer elements having different transducer spacing distances corresponding to different track spacing distances to be transduced. One of the transducer arrays may be used for transducing the tape under nominal tape track spacing conditions. Another transducer array may be used for transducing the tape when the tape track spacing is reduced due to the tape shrinkage. Still another transducer array may be used for transducing the tape when the tape track spacing is enlarged due to tape expansion.

A tape recording head is provided comprising a support plate having a contoured surface with an opening in the contoured surface which allows head chips to protrude far enough to allow proper head tape contact for recording. The support plate is fixed on a coarse actuator so that the support plate and coarse actuator move together perpendicular to the motion of the recording tape. The head chips comprising rowbar substrates containing a multiplicity of recording elements are supported on a carrier mounted on a fine actuator and are not fixed to the support plate to allow low mass fine actuation.

In a magnetic tape system, during lateral repositioning of a tape head between servo bands, the servo head is not on a servo band and is unable to provide servo position information. Hence, information about the lateral position may be lost. A control system selectively senses data read transducers of the tape head; and, upon detecting a servo signal of a servo band from a sensed data read transducer, determines the lateral position of the tape head with respect to the detected servo band based upon the position of the data read transducer that sensed the detected servo signal.

A magnetic head according to one embodiment includes outer modules each having a tape bearing surface and an array of transducers selected from a group consisting of readers and writers; and an inner module positioned between the outer modules, the inner module having a tape bearing surface and an array of transducers selected from a group consisting of readers and writers, wherein portions of edges of the tape bearing surface of the inner module are non-skiving in regions not aligned with the array of transducers in a direction of media travel thereacross, wherein an outer edge of the tape bearing surface of each of the outer modules are adapted for skiving air from the magnetic medium when the magnetic medium travels in a direction from the respective outer module towards the inner module.

A planar write module and a hybrid planar write-vertical read bidirectional tape head comprising the write module and one or more vertical read modules. The write module has a write module tape bearing surface for engaging the magnetic recording tape. Plural write elements in the write module each comprise plural thin film layers oriented in generally parallel planar relationship with the write module tape bearing surface. The write elements are arranged so that the transducing gaps (write gaps) of adjacent write elements are generally aligned in a direction that is transverse to a streaming direction of the magnetic recording tape. Each read module has a read module tape bearing surface for engaging the magnetic recording tape. Plural read elements in the one or more read modules each comprise plural thin film layers oriented in generally perpendicular relationship with the read module tape bearing surface.

A tape head assembly for writing data to and reading data from a tape includes a tape head member having an engagement surface that is configured to engage the tape as the tape moves past the tape head member. A plurality of arrays of interactive elements are supported on the engagement surface. Each array is longitudinally offset from each other array. Each individual array includes a read group having only read elements and a write group having only write elements. Each read group is laterally offset from each write group within each array.
