1. A method for providing a structure in a magnetic recording transducer comprising:
plating a first layer in a plating bath using a first plurality of plating conditions, the first layer having a first galvanic potential;
modifying at least one of the plating bath and the first plurality of plating conditions to provide at least one of a modified plating bath and a second plurality of plating conditions;
plating a second layer using the at least one of the modified plating bath and the second plurality of plating conditions so that either the first layer is between the second layer and a third layer such that the second layer does not directly contact the third layer or the second layer is between the first layer and the third layer such that the first layer does not directly contact the third layer, the at least one of the modified plating bath and the second plurality of plating conditions being selected such that the second layer has a second galvanic potential;
wherein if the first layer is between the second layer and the third layer then the first galvanic potential is between the second galvanic potential and a third galvanic potential of the third layer such that the second layer is less likely to corrode than if the second layer directly contacted the third layer; and
wherein if the second layer is between the first layer and the third layer then the second galvanic potential is between the first galvanic potential and the third galvanic potential of the third layer such that the first layer is less likely to corrode than if the first layer directly contacted the third layer;
wherein the third layer is an ambient layer.
2. The method of claim 1 wherein the first layer is a Ni1-xFex layer and the second layer is a Ni1-yFey layer, where x is at least 0.5 and not more than 0.95 and y is at least 0.18 and not more than 0.75.
3. The method of claim 1 wherein the plurality of plating conditions include a plating current and wherein the step of modifying the at least one of the plating bath and the first plurality of plating conditions further includes:
providing a step modulation change in the plating current.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. In a packaging bag, in particular of paper, plastic or a composite of these materials, having a closable top and a sound source, which produces a single or a sequence of tones, intelligible sounds or noises when the top is opened, the improvement wherein the top (2) can be closed by means of a closure means.
2. A packaging bag according to claim 1, wherein the sound source comprises a sound chip and a loudspeaker associated with it.
3. A packaging bag according to claim 2, wherein the sound source is coupled to a recording unit.
4. A packaging bag according claim 2, wherein the loudspeaker is arranged in such a way that the sound waves produced are radiated toward the outside.
5. A packaging bag according to claim 2, wherein at least one of the loudspeaker and the sound chip are arranged in the packaging bag bottom.
6. A packaging bag according to claim 1, wherein the closure means is configured in such a way that the packaging bag can be repeatedly opened and closed.
7. A packaging bag according to claim 1, wherein the closure means is selected from the group consisting of individual magnetic elements, a Velcro fastener, an adhesive glue, a ribbon and a press stud.
8. A packaging bag according to claim 1, further comprising two carrying handles arranged at the top of the bag.
9. A packaging bag according to claim 2, wherein the sound chip is coupled to a switching unit arranged at the top of the bag and configured in such a way that the sound source (10) is activated when the top is opened.
10. A packaging bag according to claim 9, wherein the switching unit is integrated in the closure means.
11. A packaging bag according to claim 1, wherein the packaging bag bottom is configured as a block bottom.
12. A packaging bag according to claim 10, wherein the closure means is a press stud.
