Abstract
According to one embodiment, a magnetic recording device based on shingled-write recording method comprises a magnetic storage medium, a recording head, and an actuator. The magnetic storage medium comprises dot rows wherein a phase shift is between adjacent rows. The recording head covers a predetermined number of dot rows of the magnetic storage medium and comprises an edge at one of the dot rows. The actuator configured to move a recording head by an amount equivalent to a dot row after recording is performed on one of the dot rows by the recording head.
Claims8
A magnetic recording device comprising:
- a magnetic storage medium comprising magnetic dot rows with a phase shift between adjacent dot rows wherein the phase shift between adjacent dot rows is (360/n) degrees, where n is an integer not smaller than two;
- a recording head configured to cover a predetermined number of dot rows and comprising an edge located at a dot row to be recorded;
- a reproducing head configured to cover a number of dot rows equal to n and to sequentially reproduce information from dots in the n dot rows along a direction of dot rows;
- a first actuator configured to move the recording head from the dot row to an adjacent dot row after recording is performed on the dot row by the recording head;
- and
- a second actuator configured to move the reproducing head by n dot rows after reproduction is performed from the n dot rows by the reproducing head, and
- thereby recording information based on a shingled-write recording method.
A magnetic recording method for a magnetic storage medium comprising magnetic dot rows with a phase shift between adjacent dot rows wherein the phase shift between adjacent dot rows is (360/n) degrees, where n is an integer not smaller than two, the method comprising:
- locating an edge of a recording head at a dot row to be recorded and recording information on the dot row wherein the recording head is configured to cover a predetermined number of dot rows;
- locating a reproducing head at a number of dot rows equal to n and sequentially reproducing information from dots in the n dot rows along a direction of dot rows wherein the reproducing head is configured to cover a number of dot rows equal to n;
- moving the recording head by one dot row and sequentially recording information on each dot row based on a shingled-write recording method;
- and
- moving the reproducing head by n dot rows after reproduction is performed from the n dot rows by the reproducing head.
A magnetic recording device comprising:
- a magnetic storage medium comprising magnetic dot rows with a phase shift between adjacent dot rows wherein the phase shift between adjacent dot rows is (360/n) degrees, where n is an integer not smaller than three;
- a recording head configured to cover a predetermined number of dot rows and comprising an edge located at a dot row to be recorded;
- a reproducing head configured to cover a number of dot rows equal to n and to sequentially reproduce information from dots in the n dot rows along a direction of dot rows;
- a first actuator configured to move the recording head from the dot row to an adjacent dot row after recording is performed on the dot row by the recording head;
- and
- a second actuator configured to move the reproducing head by n dot rows after reproduction is performed from the n dot rows by the reproducing head, and
- thereby recording information based on a shingled-write recording method.
A magnetic recording method for a magnetic storage medium comprising magnetic dot rows with a phase shift between adjacent dot rows wherein the phase shift between adjacent dot rows is (360/n) degrees, where n is an integer not smaller than three, the method comprising:
- locating an edge of a recording head at a dot row to be recorded and recording information on the dot row wherein the recording head is configured to cover a predetermined number of dot rows;
- locating a reproducing head at a number of dot rows equal to n and sequentially reproducing information from dots in the n dot rows along a direction of dot rows wherein the reproducing head is configured to cover a number of dot rows equal to n;
- moving the recording head by one dot row and sequentially recording information on each dot row based on a shingled-write recording method;
- and
- moving the reproducing head by n dot rows after reproduction is performed from the n dot rows by the reproducing head.
