Abstract

The apparatus conserves space on a record media. This is realized by eliminating extra space normally required between each of successive recorded tracks on a record media. In drawing A, magnetic head 1 is mounted on arm 2 for reciprocation in bearings 3 and 4 as indicated by arrow 5. Such is under control of link 6 that is moved to and from positions 6a and 6b. Head 1 is shown in more detail at B and is provided with two record gaps and two erase gaps arranged on either side of a V-shaped pole piece.

Recording Apparatus

The apparatus conserves space on a record media. This is realized by eliminating extra space normally required between each of successive recorded tracks on a record media. In drawing A, magnetic head 1 is mounted on arm 2 for reciprocation in bearings 3 and 4 as indicated by arrow 5. Such is under control of link 6 that is moved to and from positions 6a and 6b. Head 1 is shown in more detail at B and is provided with two record gaps and two erase gaps arranged on either side of a V-shaped pole piece.

The magnetic recorded pattern indicated on record media 7 is achieved by disposing the two sets of gaps at 45o in relation to the path traced by head 1 and by tipping the latter at the end of each scan. Head 1 has extension 8 that cooperates with stops 9 and 10 at the end of each scanning track. With head 1 pivotally mounted on arm 2, head 1 flips back and forth to the two conditions shown at C and is stepped from one track to the next. With the alternate pivoting of head 1, bits in the magnetic tracks recorded on record media 7 are disposed at 90 degrees to one another in alternate tracks. With a 90 degree displacement, cross talk between adjacent tracks is minimized and the bits are recorded adjacent to one another without a guard interval between each track.

Drawing D shows another arrangement of a head 12. Its pole piece 12a has extension 13 arranged for engagement with stops 14 and 15 to flip pole piece 12a at the end of travel as head 12 sc...
