Method and apparatus for storing and retrieving user data from magnetic recording tracks in a data storage device. In some embodiments, a rotatable data recording medium has a circumferentially extending data track formed from spaced apart embedded servo wedges that extend radially across a recording surface of the medium to define intervening data wedges between each adjacent pair of the servo wedges. Each data wedge along the data track has only a single timing field at a beginning portion of the data wedge immediately adjacent a first servo wedge, followed by a plurality of data sectors that extend across the data wedge to an end portion of the data wedge immediately adjacent a second servo wedge. No inter-sector gaps are provided between the respective data sectors and no additional timing fields are provided between the first and second servo wedges.
