A data storage device is disclosed comprising at least one head configured to access a magnetic tape comprising a plurality of data tracks, wherein each data track comprises a plurality of data segments and a plurality of servo sectors. The head is used to read one of the servo sectors to generate a first read signal. The first read signal is processed to generate a position error signal (PES) of the head relative to the magnetic tape, wherein the head is positioned relative to the magnetic tape based on the PES. The head is used to read one of the data segments to generate a second read signal, wherein the second read signal is processed to detect user data recorded in the data segment.

A tape embedded drive can include tape media for storing data, a first tape reel and a second tape reel, each coupled to one end of the tape media, and a head stack assembly (HSA). The HSA can include a first head assembly having at least one read head and one write head and a second head assembly having a non-operable head incapable of reading or writing. In an embodiment, the first head assembly is configured to be placed along a first side of the tape media and the second head assembly with the non-operable head is configured to be placed along a second side of the tape media opposite the first side of the tape media.

The magnetic tape in which a difference (S.sub.0.1−S.sub.1.6) between a spacing S.sub.0.1 and a spacing S.sub.1.6 obtained after n-hexane cleaning on a surface of the magnetic layer is equal to or less than 32 nm. The S.sub.0.1 is a value obtained as a spacing under a pressing force of 0.1 atm from a relational expression between a pressure and a spacing obtained by performing a spacing measurement on the surface of the magnetic layer by an optical interference method under a pressing force of each of a plurality of different pressures after the n-hexane cleaning, and S.sub.1.6 is a spacing measured on the surface of the magnetic layer by the optical interference method under the pressing force of 1.6 atm after the n-hexane cleaning.

The present disclosure generally relates to a tape embedded drive having a head-gimbal assembly (HGA) and a contact plate. By using a support structure or contact plate beneath the tape, read and write heads can be designed to be narrower than the tape. The support structure or contact plate can stretch or relax the tape so that the spacing between servo tracks on the tape corresponds to the servo to servo spacing on the head. HGAs, which are narrower than the tape, can fly over the tape and read data from and write data to the tape. The HGA can have a single head or multiple heads. Additionally, multiple independent head assemblies can also be used for reading from and writing to the same tape.

A gap is positioned between the closure and the substrate, the gap having an array of magnetic transducers extending therealong and unpatterned films. The gap further includes a first layer of a first material having a bulk modulus of elasticity lower than the unpatterned films in the gap. An apparatus according to another embodiment includes a plurality of magnetic transducers arranged in a linear array, and a layer of an expansion material between each adjacent pair of magnetic transducers in the array. An encapsulant is positioned between each layer of the expansion material and the adjacent magnetic transducers. The expansion material has a greater coefficient of thermal expansion than the encapsulant.
