Abstract: Disclosed is a solenoid-operated valve which hardly brings a plunger into a lock and is capable of improving its responsivety. In the solenoid-operated valve, the plunger slidably guided in an inner bore formed in a yoke and a core aligned axially is moved by energizing an electromagnetic coil, and a spool in a valve section is moved through a rod portion which protrudes from an end of the plunger to pass through a center hole of the core. An electromagnetic section fluid chamber defined by a forward end surface of the plunger and the inner bore of the core communicates with an intermediate fluid chamber defined between the core and a valve sleeve, through a clearance between the center hole and rod portion. The spool is provided at one end thereof with a land portion whose end surface defines a part of the intermediate fluid chamber.

The detection unit 36 is used for detection coil malfunctions. The interline crosstalk amplitude detection unit 36 includes an interline crosstalk amplitude detection circuit 31 which is branched from a branch circuit 30 within the read circuit in the preamplifier 20. The interline crosstalk amplitude detection unit 36 is provided with the capability to determine occurrence of a write condition abnormality when the amplitude has exceeded a threshold value, making it possible to ensure the recording function of the preamplifier 20. Likewise, the inductance is reduced when a circulatory shunt has occurred in a line near the head, making it possible to detect a write condition abnormality.

Abstract: The magnetoresistance effect element is of a multilayered structure having at least magnetic layers and an intermediate layer of an insulating material, a semiconductor or an antiferromagnetic material against the magnetic layers, and the magnetoresistance effect element has terminals formed at least on the opposite magnetic layers, respectively, so that a current flows in the intermediate layer. The film surfaces of all the magnetic layers constituting the magnetoresistance effect element are opposed substantially at right angles to the recording surface of a magnetic recording medium. Therefore, the area of the magnetic layers facing the recording surface of the magnetic recording medium can be extremely reduced, and thus the magnetic field from a very narrow region of the high-density recorded magnetic recording medium can be detected by the current which has a tunneling characteristic and passes through the intermediate layer.

Abstract: Data byte errors are detected by a comparator and classified into errors for respective interleaves, and the classified errors are counted by counters in an error count block. Further, at the time one sector has been read, comparators compare the counted values for the respective interleaves with an interleave threshold to detect whether nor not there are interleaves which have a number of errors exceeding the interleave threshold, and the detected results are counted by an error count block. The frequency of retries after an ECC is predicted from the counted value on the error count block and the total number of read sectors.
