Apparatus and method for writing data on a tape medium
First Claim
1. An apparatus comprising:
- a write unit configured for writing first data accumulated in a buffer on a tape medium in a first position extending over a first track and an area adjacent to the first track, writing second data accumulated in the buffer on the tape medium in a second position extending over a second track and an area adjacent to the second track, and writing the first data and the second data in a third position extending over a third track and an area adjacent to the third track; and
a processing unit configured for preventing the first data written in the first position from being overwritten with the first data written in the third position by, before the first data is written in the third position, determining whether the first data written in the first position is to be overwritten with the first data written in the third position.

Abstract
An apparatus and method are disclosed for writing data accumulated in a buffer on a tape medium in such a way that overwriting is prevented. The apparatus comprises a write unit configured for writing first data in a first position extending over a first track and an area adjacent to the first track, writing second data in a second position extending over a second track and an area adjacent to the second track, and writing the first data and the second data in a third position extending over a third track and an area adjacent to the third track. Furthermore, the apparatus comprises a processing unit configured for preventing the first data written in the first position from being overwritten with the second data written in the second position or with the first data written in the third position.

5. A method comprising:
-
writing first data accumulated in a buffer on a tape medium in a first position extending over a first track and an area adjacent to the first track; writing second data accumulated in the buffer on the tape medium in a second position extending over a second track and an area adjacent to the second track; preventing the first data written in the first position from being overwritten with the first data written in a third position extending over a third track and an area adjacent to the third track by, before the first data is written in the third position, determining whether the first data written in the first position is to be overwritten with the first data written in the third position; and upon determining that the first data written in the first position is not to be overwritten with the first data written in the third position, writing the first data and the second data in the third position. - View Dependent Claims (6, 7, 8)

9. An apparatus comprising:
-
a write unit configured for writing first data accumulated in a buffer on a tape medium in a first position extending over a first track and an area adjacent to the first track, writing second data accumulated in the buffer on the tape medium in a second position extending over a second track and an area adjacent to the second track, and writing the first data and the second data in a third position extending over a third track and an area adjacent to the third track; and a processing unit configured for preventing the first data written in the first position by the write unit from being overwritten with the second data written in the second position by interposing the second track between an area adjacent to the first track and a fourth track used subsequent to the third track, and by setting the second position at a position extending over the second track and the fourth track. - View Dependent Claims (10, 11, 12, 13)
