A method for making a magnetic recording tape, in accordance with one approach, includes coupling an underlayer to a substrate, the substrate comprising a poly ether ether ketone (PEEK). A method for making a magnetic recording tape in accordance with another approach includes coupling an underlayer to a substrate via radiation-induced grafting, the substrate comprising a poly ether ether ketone (PEEK). A recording layer may be coupled to the underlayer.

The present disclosure generally relates to a head assembly of a data storage device. The data storage device may include magnetic media embedded in the device or magnetic media from an insertable cassette or cartridge (e.g., in an LTO drive), where the magnetic head assembly reads from and writes to the magnetic media. During drive operation, the magnetic media moves across the magnetic head assembly. The magnetic head assembly is spaced a distance from the magnetic media such that non-contact recording occurs between the magnetic head assembly and the magnetic media. The magnetic media is supported by either a back plate or an air film generated by one or more fillet edges of the back plate and the velocity of the magnetic media as the magnetic media moves across the magnetic head assembly.

The present disclosure generally relates to a head assembly in a data storage device. The data storage device may include magnetic media embedded in the device or magnetic media from an insertable cassette or cartridge (e.g., in an LTO drive), where the head assembly reads from and writes to the magnetic media. During device operation, the magnetic media moves across the head assembly. The magnetic media experiences higher contact stress at certain points or portions of the head assembly. A sensor guard is coupled to the head assembly. The sensor guard comprises at least one chamfered surface or at least one stepped surface to decrease the contact stress between the magnetic media and the head assembly during device operation. The at least one chamfered or stepped surface may be disposed on a leading edge of the sensor guard.

A magnetic recording tape, in accordance with one approach, includes a substrate comprising a poly ether ether ketone (PEEK). An underlayer is positioned above the substrate. A recording layer is positioned above the underlayer. A tape cartridge, in accordance with one approach, includes a housing and a magnetic recording tape at least partially stored in the housing. The magnetic recording tape includes a substrate comprising a poly ether ether ketone (PEEK), an underlayer above the substrate, and a recording layer above the underlayer.

A magnetic tape cartridge including: a magnetic tape; and a recording medium including a predetermined area for recording defect information, which is information regarding a defect of the magnetic tape detected in a production process of the magnetic tape. A recording device, a recording method, a data recording and reproducing system, and a data recording and reproducing method are also provided.

A storage device comprises tape reel(s) holding tape media for storing data, a head assembly, motor(s) configured to actuate the head assembly, a sealed casing, and a printed circuit board assembly (PCBA) configured to control operations of the motor(s). The head assembly comprises a support structure, a head bar with read head(s) and write head(s), and a suspension system connecting the head bar to the support structure. The sealed casing encloses in its interior the tape reel(s), the head assembly, and the motor(s). Meanwhile, the PCBA is mounted on an external surface of the casing.
