这有什么,我的理解就是复合磁头,而且铁氧体也是最好的磁头材料之一,并没有淘汰一说,有卡友评价索尼的s&f磁头是最好的磁头
Most manufacturers switched to Sendust and Ferrite compostion heads because the sendust had much lower eddy current losses at higher frequencies than traditional ferrite heads, although wear was an issue. At normal-expected-life for a tape deck, wear wasn't that big an issue but improved HF response by using Sendust compostion heads was a big plus. Thus the better decks went away from ferrite&ferrite to sendust&ferrite. |
