    • Provided is a magnetic recording apparatus including a magnetic recording medium having a magnetic recording position patterned of a magnetic substance and a read head reading information from the magnetic recording medium, wherein the magnetic recording medium includes: a data area having the magnetic recording position patterned including a plurality of data tracks; and a servo area including a servo burst for tracking the data tracks, wherein the servo burst includes a plurality of bursts deviating from one another in a downtrack direction, and a width of each of the bursts is equal to or greater than a width of the read head and narrower than twice the width of the read head. According to this structure, although data is reproduced using a read head having a greater width than a width of each of data tracks, a linear section in which an output voltage is reduced depending on a size of an off-track is formed. As a result, a dead zone can be removed.
    • 本发明提供一种磁记录装置,包括磁记录介质,磁记录介质具有图形化的磁性物质和从磁记录介质读取信息的磁头,其中磁记录介质包括:具有磁记录位置图形化的数据区,包括 多个数据轨道; 以及包括用于跟踪数据轨道的伺服脉冲串的伺服区域,其中所述伺服脉冲串包括在倾斜方向上彼此偏离的多个脉冲串,并且每个脉冲串的宽度等于或大于 读头并且窄于读头宽度的两倍。 根据该结构,虽然使用宽度大于数据磁道的宽度的读头来再现数据,但是形成其中输出电压根据偏离磁道的尺寸减小的线性部分。 因此,可以去除死区。
