    摘要: An integrated read/write perpendicular recording head facilitates the use of magnetic storage media having a high magnetic recording density and high data rates. The use of a perpendicular write portion provides adequate space between the main and opposing poles for a read element and associated electrical contacts therebetween. The use of a differential dual spin valve as a read element eliminates the need for magnetic shielding of the read element. Such a structure permits the read element and main write pole to be close together, thereby minimizing seek time, and permitting rapid transition from read to write operations, and vice versa.
