摘要： PURPOSE:To eliminate instability of tape feeding due to influence of a rotary drum and complexity of a tape loading mechanism by reducing the winding angle of a magnetic tape on the drum to smaller than 180 deg.. CONSTITUTION:Output image data of a channel encoder 11, output audio data of an audio signal encoder 11 and output additional code of an additional code generator are recorded on a magnetic tape 78 by magnetic heads 13A, 13B mounted on a rotary drum. The image data, the audio data and the additional code are recorded in a predetermined array on the tape 78, and the winding angle theta of the tape 78 on rotary drums 76, 77 is set to smaller than 180 deg.. Thus, instability of tape feeding due to influences of the rotating drums 76, 78, complexity of a tape loading mechanism are eliminated.

摘要： PURPOSE:To record for a long time by using a small-sized tape cassette by using a magnetic tape having a thin thickness and a narrow width. CONSTITUTION:Output data of a channel encoder 11 is recorded on a magnetic tape 78 by magnetic heads 13A, 13B. In this case, the thickness of the tape 78 is 7mum or less, the width is 8mm or less, and the tape 78 having a length capable of recording at least a standard video signal for a long time is contained in a tape cassette, and operated. Thus, a magnetic recorder of a digital image signal capable of recording for a long time by a small-sized tape cassette is obtained.

摘要： PURPOSE:To control thrust force even after assembly by adjusting the position of a sleeve member, which is externally fitted through a fluid bearing to a support shaft, in the axial direction of the support shaft, and varying a distance between the gap of a rotary transformer and the thrust yoke of a thrust magnet. CONSTITUTION:When adjusting the position of a sleeve member, which is externally fitted through the fluid bearing to a support shaft 3 so as to be rotated, in the axial direction of the support shaft 3, the fitting height positions of magnetic heads 29 and 30, the distance between first-order coils 22 and 26 and second-order coils 23 and 25 in rotary transformers 24 and 27 and between a thrust magnet 18 and a thrust yoke 19 can be made variable. Therefore, without enlarging the movable amounts of the magnetic heads 29 and 30 to members for supporting these magnetic heads, the fitting height positions of the magnetic heads 29 and 30 can be easily controlled. Thus, the so-called thrust force for controlling the gaps of the rotary transformers 24 and 27 and for positioning the rotary head can be easily adjusted even after the assembly.

摘要： PROBLEM TO BE SOLVED: To stably execute focus bias calibrations. SOLUTION: In a step S51, a DSP(digital signal processor) writes dummy data in the sector for calibration of a MO disk. In a step S52, the DSP reads out the sector for calibration by successively changing defocusing amounts to -20%, -10%, 10%, 20% and it corrects the gain of a tracking error signal by dividing respective obtained tracking error signals by correlation values among correlation values D1 to D4 corresponding to the defocusing amounts. At the same time, the DSP obtaines jitter corresponding to defocusing amounts measured by a read channel part from a jitter register in the read channel part.

摘要： PROBLEM TO BE SOLVED: To enable restoration processing by detecting defect of operation of an optical block. SOLUTION: A controller 8 controls a DSP 10, and makes an optical block 3 output a slide servo signal moving to a most inner peripheral side of MO media 1 to a slide driver 13. The controller 8 discriminates whether a position of the optical block 3 is moved to the most inner peripheral part of the MO media 1 within 200 ms after this command. When it is discriminated that the position of the optical block 3 is not moved to the position corresponding to the most inner peripheral part of the MO media 1, the controller 8 makes the DSP 10 output the slide servo signal being a sine wave to the slide driver 13. The slide driver 13 applies voltage being the sine wave to a slide motor 3b based on this slide servo signal. Thereby, as the optical block 3 is swung on an axis 3a, restoration processing from impossibility of operation due to hardening of grease and impossibility of operation due to a minute foreign matter can be performed.

摘要： PROBLEM TO BE SOLVED: To improve the stability of tape running with a simple constitution by arranging a rotating body pivotally supported by a bearing so that its axis of rotation is inclined in the center direction of a tape lead part and forming the center part of the tape lead part to a projecting shape relatively to the track of magnetic head rotation. SOLUTION: A fixed shaft 12 is fixed to a lower fixed drum 11 at a prescribed angle θ to the center of a tape lead part 18 with respect to a reference line Z perpendicularly extended from the center of the lower fixed drum 11 and is inclined with the intersection between a rotation axis Y of a magnetic head 15 and the reference line Z as the center. When the magnetic tape is run, the tape lead part 18 has a projecting shape having a prescribed extent of projection (h) to form the prescribed angle to the track of running of the magnetic head 15, and the fixed shaft 12 is inclined in the center direction of the tape lead part 18. Consequently, the tape doesn't come close to the tape lead part 18 more than necessary on the tape entrance side and exit side of the tape lead part 18, and contact is prevented to stably run the tape.

摘要： PROBLEM TO BE SOLVED: To surely perform the reading of format information by determining an optical block position so that the laser beam emitted from an optical block is irradiatated on the format information recorded in the prescribed area of a disk shaped recording medium. SOLUTION: A digital signal processor DSP 3 makes a laser beam L1 having a prescribed light intensity irradiate on a magneto-optical disk 7 by controlling the laser light source of an optical block 9 via a laser controller 8. After the RF signal S18 obtained by photoelectrically converting a reflected light L2 from the recording area PEP of the format information of the magneto-optical disk 7 with the photodetector being in the optical block 9 is subjected to a digital convertion in a lead channel 16, the converted digital signal is made format data D4 and format information are obtained by decoding the format data D4 in the DSP 3. Here, the intensity of the laser beam L1 to be emitted from the optical block 9 and the transformation system of recording data D1 in a controller 2 or the like are changed over by discriminating types of media of the magneto-optical disk 7.
