A magnetic recording method, system and apparatus are described to increasing areal density capability (ADC) for a data storage system, where in different data tracks were written with different write configurations or with different writers in a particular way that is optimized to improve areal density for a data storage device. In an aspect, the data tracks were labeled as bottom, middle or top tracks, the write order follows in a particular way among different tracks, middle and top tracks partially trim the previously written track from one side. The distance between neighboring tracks, or the percentage of track trimmed, depend on the labels they have and the drive architecture used, are different. The particular write order can be in sequential or can have a certain level of randomness as set by the drive. The write order for each operation depend on the label determined by the drive for a given drive capacity requirement. For the apparatus to enable such approach, additional alignment condition between readers, writer, heater and temperature sensor are also optimized to improve performance, areal density and reliability.
A blocked magnetic recording method with the recorded data on a magnetic media, where the data tracks can be labeled as top, middle and bottom tracks, and in the write process, the bottom track is written before middle and top tracks next to it;
A blocked magnetic recording method with the recorded data on a magnetic media, where the data tracks can be grouped into bands, each band includes more than one tracks and within each band, the data tracks can be labeled as top, middle and bottom tracks, where the neighboring bands have tracks partially trimmed from opposite sides.
The method to achieve blocked magnetic recording configuration of claim 16, where in rewrite new data into different band involve read verification process.
A magnetic recording method including an integrated magnetic recording head with one or two writers, one or two read sensors, at least one temperature sensor and at least one heater is energized during read and write processes to enable low head media separation. The recorded data is on a magnetic medium, where the data tracks can be labeled as top, middle and bottom tracks. In the write process, the bottom track always written before the middle track next to it, the middle track is written before the top track next to it.
