Title: Circuit arrangement to process an analogous reading signal in a rotating bulk memory
Inventor: KRANABETTER JOHANN
IPC: G11B5/09
Filed: 1986-08-18
Granted: 1989-07-06
Abstract: In rotating mass memories, for example magnetic disk memories, write or, respectively, read operations are controlled by a static status signal. A plurality of read heads having assigned preamplifiers is selectively activatable with the assistance of a selection signal and is through connectible to a common signal shaping device for further amplification and filtering of the read output signal. The signal shaping device has an input stage assigned thereto in which the differential outputs of the preamplifiers are respectively connected in parallel to the signal shaping device via a respective coupling capacitor. The input stage also comprises first analog switches arranged between an operating voltage and the coupling capacitors and comprises second analog switches in series in the signal lines. Derived from the signal state of the status signal, these are controlled such that the coupling capacitors are quickly recharged by brief activation of the first analog switches given a status change and the signal lines are only switched through thereafter by closing of the second analog switches.
