Abstract
A method, and apparatus configured to perform such method, according to various embodiments, includes writing data stored in a buffer onto a recording medium using a write head in a first round of writing. An interval marker is written on the recording medium in the first round of writing when the buffer is empty. Next data is written onto the recording medium after the interval marker in the first round of writing. Data is written in an area of the interval marker in a second round of writing performed subsequent to the first round.
Claims20
An apparatus comprising:
- a controller configured to:
- write, by the controller, data stored in a buffer to a recording medium in a first round of writing;
- write, by the controller, an interval marker in the first round of writing when the buffer is empty;
- write, by the controller, next data on the recording medium after the interval marker in the first round of writing;
- and
- write, by the controller, data in an area of the interval marker on the recording medium in a second round of writing performed subsequent to the first round.
A method, comprising:
- writing data stored in a buffer onto a recording medium using a write head in a first round of writing;
- writing an interval marker on the recording medium in the first round of writing when the buffer is empty;
- writing next data onto the recording medium after the interval marker in the first round of writing;
- and
- writing data in an area of the interval marker in a second round of writing performed subsequent to the first round.
A computer program product for writing data onto a recording medium, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code readable/executable by a controller to:
- write, by the controller, data stored in a buffer onto a recording medium in a first round of writing using a head;
- write, by the controller, an interval marker on the recording medium at a location after the data;
- write, by the controller, next data on the recording medium after the interval marker marker in the first round;
- and
- write, by the controller, data stored in the buffer in an area of the interval marker in a second round performed subsequent to the first round.
