Abstract

PURPOSE:To shorten a processing time of magnetic recording by providing two write heads arranged in parallel in the center on the upper face of a magnetic recording head main body and four read head arranged before and after these write heads correspondingly to two write heads. CONSTITUTION:A first track write head 2 and a second track write head 5 are provided in parallel on the upper face of a main body 1, and first track read heads 3 and 4 and second track read heads 6 and 7 are provided before and after heads 2 and 5 correspondingly to these heads 2 and 5. Consequently, the read after write operation is performed forward and backward. Thus, the processing time is considerably shortened in comparison with conventional read after write type magnetic recording heads.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a read-after-write type magnetic recording head.

[Conventional technology]

As shown in FIG. 2, a conventional read-after-write magnetic recording head that records two tracks simultaneously has two write heads (first track write The head 9 and the second track write head 11) and two corresponding read heads (first track read head 0 and second track read head 12) are provided.

[Problem to be solved by the invention]

As mentioned above, the conventional two-track glue-door after-write magnetic recording head has two write heads and two read heads, so recording during read-after-write can only be performed in one direction. There is a drawback that it cannot be done.

For this reason, when performing read-after-write operations continuously, it is necessary to return the magnetic recording head to the home position before recording, which poses a problem in that the magnetic recording processing time takes a long time.

[Means to solve the problem]

The magnetic recording head of the present invention includes two write heads arranged in a row at the center of the upper surface of the magnetic recording head main body, and two write heads arranged in front and behind the two write heads corresponding to each of the two write heads. It is equipped with four read heads.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIGS. 1(a) and 1(b) are a plan view and a front view showing an embodiment of the present invention.

The 21-door after-rack magnetic recording head of this embodiment has a first head write head 2 and a second rack write head 5 provided in parallel on the upper surface of the main body 1, and a corresponding front and rear thereof. A first track read head 3 and 4 and a second track read head 6 are arranged.
and 7.

With the above-described configuration, it is possible to perform the read-after-write operation from either the left or right direction.

〔Effect of the invention〕

As explained below, the magnetic recording head of the present invention has two
By having four write heads and four read heads disposed both in the front and rear directions for each of the write heads,
This has the advantage that read-after-write operations can be performed in both the forward and backward directions, and therefore the processing time can be significantly reduced compared to conventional read-after-write magnetic recording heads.
