    Abstract: A combination user data signal is read from two or more inner tracks of a recording medium via a first reader that encompasses the inner tracks. First and second data signals are read from respective first and second outer tracks that surround the inner tracks via second and third co-planar readers that are on a same head-gimbal assembly as the first reader. The first reader is centered between and downtrack from the first and second co-planar readers on the read head. User data is recovered based on the combination user data signal and the first and second data signals.

    Abstract: Technologies are described herein for relaxing design constraints on magnetic recording media through the use of two-dimensional magnetic recording in a storage device. A storage device comprises a magnetic recording surface comprising a plurality of discrete storage locations formatted in an ordered pattern, the magnetic recording surface configured so that a single bit of data is stored in two or more of the discrete storage locations. The storage device further includes a read-write channel configured to utilize two-dimensional magnetic recording to read and write data to the magnetic recording surface.

    Abstract: An apparatus comprises a write transducer, an energy source, and a controller. The write transducer is configured to write data to a magnetic recording medium, and the energy source is configured to heat the magnetic recording medium while it is being written to by the write transducer. The controller is coupled to the write transducer and configured to adjust at least an operating power of the energy source to selectably cause bits having variable bit aspect ratios to be written to the magnetic media.

    Abstract: Polarity transitions of a write signal applied to a write coil correspond to first bit boundaries written to a magnetic recording media. A heat signal is applied to heat the magnetic recording media via a heat source while bits are being written. The heat signal includes negative pulses that de-energize the heat source during cooling periods corresponding to the writing of the first bit boundaries. The negative pulses are offset from the polarity transitions by a predetermined time.

    Abstract: A light delivery system in a slider includes a channel waveguide, a solid immersion mirror, a near field transducer, and a planar waveguide assembly. The solid immersion mirror focuses light to the near field transducer. In one implementation, the slider includes a first reflective element and a second reflective element formed in the slider to induce an offset between a light source and the near field transducer. The reflective elements redirect light received from a light source between the reflective elements to a focusing element (e.g., a solid immersion mirror) focused on a near field transducer. The reflective elements translate the light in accordance with the offset between the light source and the near field transducer.
