摘要： The method for determining a reproduction position of a disc player in a reproduction device which reproduces information recorded on a recording medium through movement of a reproduction unit, includes a first step for identifying a piece number of music which was being reproduced of the time of power off and a position of a reproduction unit at the time of power off when power is turned on after turned off during reproduction of the piece of music recorded on a recording medium, and a second step for moving the reproduction unit to a beginning position of the piece of music which was being reproduced at the time of power off and performing normal reproduction, and the method for determining reproduction position of a record player in a reproduction device having a reproduction unit fixed and a recording medium moving for reproducing information recorded thereon, includes a first step for, when during the reproduction of a music recorded on a recording medium power is turned off and then turned on, detecting existence of information of music from a part the reproduction unit is happened to match with at the time of turn on of pieces of music recorded on a recording medium, and a second step for finding non-existence of signal of music from the part the reproduction unit is happened to match with the recording medium at the time of turn-on and performing reproduction from the beginning of the piece of music having been reproduced at the time of turn-off.

摘要： An apparatus for positioning a magnetic tape head (3) transversely relative to a length of magnetic tape in a magnetic tape recorder along a shaft. The shaft (6) vertical axis may be slightly tilted to compensate for manufacturing tolerances and achieve the necessary alignment of the magnetic tape head to the magnetic tape (3) path. To accomplish this, one end of the shaft (6) is supported in a washer bracket (12) for connecting that end of the shaft to the tape drive frame (1). The washer bracket (12) is pre-loaded axially of the shaft (6), such that a directing force applied to that end of the shaft permits the washer bracket to slide in a direction transverse to the axial direction of the shaft on the frame. Otherwise, the washer bracket (12) frictionally abuts the frame (1) and holds that end of the shaft (6) in fixed position on the frame (1).

摘要： A recording and/or reproducing apparatus includes a detection unit for detecting a tracking error detecting pit pattern or a sector mark from a detection signal from an optical head adapted to record and/or reproduce data signals on or from an optical disk, on which tracking error detecting pits or sector marks are accorded with a predetermined offset from the center of the recording track. The detection unit is adapted for detecting the tracking detecting pit pattern or the sector mark on the basis of the bit data pattern and the amplitude pattern of the detection signal from an optical head.
