Abstract

According to one embodiment, there is provided a magnetic recording apparatus including a head slider including read and write elements, and a magnetic recording medium including magnetically recordable recording tracks with a width L 1, a wide land track with a width L 2 larger than the width L 1 of the recording track, and non-recording sections with a width G 1 each provided between adjacent recording tracks. The width L 1 of the recording track is smaller than a bottom read width BRW of the read and write elements, and the width L 2 of the wide land track is larger than the bottom read width BRW of the read and write elements.

Claims

exact text as granted — not AI-modified
1 . A magnetic recording apparatus comprising:
 a head slider comprising read and write elements; and   a magnetic recording medium comprising:
 a plurality of magnetically recordable recording tracks, the plurality of recording tracks comprising a magnetic land width L 1 ; 
 a wide land track having a magnetic land width L 2  larger than L 1 ; and 
 a plurality of non-recording sections, including a first non-recording section comprising a width G 1 , each of the plurality of non-recording sections provided between adjacent recording tracks, 
   wherein magnetic land width L 1  is smaller than a bottom read width BRW of the read and write elements, and the magnetic land width L 2  is larger than the bottom read width BRW of the read and write elements.   
     
     
         2 . The apparatus of  claim 1 , wherein the wide land track includes a second non-recording section with a width G 2  larger than the bottom read width BRW of the read and write elements in a sweep width of the head slider. 
     
     
         3 . The apparatus of  claim 2 , wherein the second non-recording section is adjacent to the wide land track. 
     
     
         4 . A method of testing the magnetic recording apparatus of  claim 1 , comprising:
 performing a test using the wide land track, the test being selected from the group consisting of a test for a flying height of the head slider, a test for a voltage and a current of the read and write elements, and a signal degradation test.   
     
     
         5 . A method of testing the magnetic recording apparatus of  claim 2 , comprising:
 performing a test for magnetic characteristics of the first non-recording section using the second non-recording section.
